Journey Through the History of Baseball

You have presumably heard that baseball is America’s national pastime. That’s because the USA is considered the motherland of this popular sport and plays a significant role in the history of baseball

Even though baseball is an international sport today, America’s role in its invention and spreading remains crucial.

When I look at the history of baseball, I can understand why baseball is more than a sport. It’s a national tradition, attended, and watched by people from 7 to 77 years old. 

Now, the time has come to discover why this game is the centrepiece of American sports and how it all began.

Was baseball invented in America, and most importantly, how was baseball invented?

How did baseball become what it is today, and what are the most critical events in the baseball history timeline?

If you are ready, let’s dive deeper into baseball’s history and learn everything about this exciting game, its roots, beginnings, leagues, players, and legacy.

The History of Baseball

19th Century Baseball 

During the 19th century, baseball underwent a remarkable metamorphosis, transitioning from a rudimentary pastime to a structured sport.

The decade-by-decade evolution brought innovations like the nine-player team, nine-inning games, and standardized rules. The Civil War also played a role, in spreading the game and fostering its popularity. These developments laid the groundwork for the modern sport we cherish today.

Baseball’s Origins

Baseball fans often pose a question: Is baseball based on cricket? I can answer with yes; it probably is in some way.

Early baseball originated from two English games: cricket and rounders, brought to the USA by early colonists. 

I’m familiar that games with a bat and ball were played in England in the 18th century, and obviously, which were later brought to America. 

Knowing this, you may wonder, what was baseball originally called? 

During the 1850s, the game in New York was called town ball, baseball, round town, and other similar names.

Then, how did baseball get its name?

Baseball history facts show that the name baseball originated in England and was together with the game brought to the States. The game’s name appears in a book from 1744 called Little Pretty Pocket-Book.

Where was baseball first played?

How was baseball invented? Well, the question is still disputed until today. But, for that later.

However, the early origins of baseball play in America date somewhere in the mid-18th century, during the American Revolution. 

Early baseball games were first played in schools and university campuses nationwide during those times.

Later, amateur baseball became immensely popular among workers and spread in 19th-century industrialized cities.

That’s why the 19th century can be considered the birth era of the sport. Not only because baseball started advancing but also because baseball became a professional sport during the century.

The myth about the invention of baseball

For many years it was believed that Abner Doubleday was the father of baseball, and he invented the sport. 

Historians and fans still argue whether this is just a legend or whether Abner Doubleday was the founder of America’s favorite sport. 

According to the story, Abner Doubleday was an American Civil War General who invented baseball in 1839 in Cooperstown, New York. However, specific sources claim that Abner Doubleday neither invented baseball nor was in Cooperstown then. 

The debate continues: was the story about Abner Doubleday promoted just to convince people that the game originated in the USA?

Regardless of whether a myth or truth, Abner remains a critical mark in the history of baseball.

Early Beginnings 

The first unprofessional baseball club 

The first amateur baseball team, Knickerbocker, was formed in September 1845 by a group of New York men.

According to baseball history, Alexander Joy Cartwright, who was part of this club, invented new rules for the baseball game. 

Consequently, these rules, including the diamond-shaped infield and the three-strike rule, among others, laid the foundations for modern baseball.

When was the first baseball game?

According to baseball history facts, the Knickerbockers played their first official game in 1846. In other words, the game was played on June 16th, 1846, at the Elysian Fields. The Knickerbockers played against New York Nine and lost. 

The Rules of Baseball

Baseball evolved through the years thanks to many passionate Americans.

Considering that baseball didn’t have an official “birth” and was created following other games at the time, I can’t solve the debate around its origins. 

I can only express that the game matured between 1800 and 1900, with its rules frequently changing and updating.

Here, I must mention the famous baseball father Doc Adams, or Daniel Lucious “Doc” Adams, who had handwritten some of the earliest baseball rules. It’s also good to know that Adams was the president of the Knickerbockers. 

The rise of professional baseball

I can point out that professional baseball officially started in the late 19th century with the formation of the first professional baseball team, Cincinnati Red Stockings. 

According to the baseball history timeline, the National Association of Professional Baseball Players (NAPBBP) formed in 1871, developed the club in New York. 

However, one of the most crucial dates in baseball’s history is the National League‘s appearance. 

On February 2, 1876, the National League (NL) was founded at a meeting in New York, encouraged by the owner of Chicago White Stockings, William Hulbert.

At that time, the league members were: Chicago White Stockings, Boston Red Caps, Hartford Dark Blues, Cincinnati Red Stockings, Louisville Grays, St. Louis Brown Stockings, New York Mutuals, and Philadelphia Athletics.

Afterward, other baseball leagues were formed, such as the American Association (AA), the main rival of the NL. 

20th century baseball

The 20th century was a critical age in the history of baseball because during this time. 

We already know that the rules were roughly established during the 19th century, but at the beginning of the 1900s, they underwent changes, and many new elements were added. 

Hence, the 20th century is often referred to as the baseball century—an era when the game grew in popularity and evolved massively into what we call modern baseball today. 

The emergence of the American League

The American League (AL) originated from the minor Western League, which, thanks to Ban Johnson, was renamed and revolutionized in 1900. However, in 1900 the AL was still minor until Ban Johnson decided it was time to rival the NL in 1901. 

AL moved its headquarters and teams to Boston and Philadelphia-NL teams’ cities. AL started signing NL players, and the two leagues spent two years in conflicts and feuds. 

Officially, peace was signed in 1903 with the National Agreement, and the champions of AL and NL decided to meet in the First World Series.

Since 1903, the World Series has been a championship between the two Major Baseball Leagues (MBLs), with the winning team being the World Champion

As a passionate baseball lover, I regard these moments as crucial in the history of baseball because the emergence of the AL was necessary for the evolution and organization of professional baseball.

The peace between the two leagues brought significant progress, and because of their coexistence on the field, baseball’s interest and attendance grew further. 

The Deadball Era

It’s widely believed that the Deadball Era started with the emergence of the AL as a major league.

The Deadball Era of baseball, named after the “dead” softball, plays a vital role in the history of baseball because, during this time, the sport became more stable and arranged

The Deadball era was based on low scoring and giving importance to pitching and defense. Seemingly, that contributed to the changing of baseball rules and gameplay. 

One of the main reasons for the Deadball era to rise to power was the “Foul strike” rule, or the counting of foul balls as strikes. This rule gave more attention to baseball’s defenses, which was not the case until then.

The Spitball

Pitchers ascended during the Deadball era because of the Spitball, which later became illegal

Using saliva or other slippery material for the ball gave pitchers a significant advantage over hitters, and many skilled pitchers topped the Deadball era. Some of them are Cy Young, Christy Mathewson, and Walter Johnson.

Still, the Deadball era gave birth to some of the most talented hitters, who attacked the ball instead with skill rather than aggression. Among them are Ty Cobb, Joe Jackson, and Honus Wagner.

The Deadball era ended in 1919 with the Black Sox Scandal; Spitball was banned, and baseball’s construction underwent other changes.

The Impact of Babe Ruth

Babe Ruth’s rise was another reason for the Dead Ball Era’s unlucky fate. 

Babe Ruth, or the man, the myth, and the legend of baseball, remains the most indispensable player in the history of baseball, not only for me but for the whole nation. 

He prioritized hitting home runs with one hard and free swing, later inspiring other baseball players. He emphasized baseball’s offense instead of defense, and batting and home runs flourished during his time and after. And these are just some of his contributions to the game.

His charisma, talent, full-swing hitting, and records gave prominence to a new period, the Live Ball era

During the Sultan of Swat’s time, baseball statistics massively changed. Specifically, stolen bases decreased compared to runs and home runs, which dramatically increased.

This considerable advancement in the baseball game attracted more stadium fans, and attendance at baseball games soared. 

Babe Ruth ended his career in 1935 with 714 home runs, 2873 hits, 506 doubles, and 2174 runs

Baseball during World War II and the Integration

World War II

Some may expect that baseball’s popularity decreased during WWII, but that’s untrue. Even though baseball was played less during these times, its recognition rose. 

It’s also crucial to note that before WWII began, some of the grandest baseball stars emerged. Joe DiMaggio set a record with hits in 56 consecutive games, while Ted Williams batted 406

I can note that during WWII, baseball increased the citizen’s morale. The persistence of the games on the field gave every American entertainment and a boost during the hardships of the war.

With President Theodore Roosevelt’s “Green Light Letter,” baseball continued its existence and importance during the war, although many ML players were off to fight. 

Baseball was the only American National Sport during WWII, and many people found solace in the matches.

The game acted as a healthy distraction, and even though many ML players served, the attendance of the games didn’t drastically fall. 

After the war, the sport didn’t only survive, but it became more of an American’s favorite national pastime. 


Another essential part of the history of baseball was racial integration. African-Americans were already politically influential in the 1940s, and many were successful in exhibition baseball games. 

One of the factors that probably led to the integration was the participation of African-Americans in WWII. 

Integration had to happen, and dark–colored players had to be recognized and not separated in “colored” leagues. And, luckily, it did. 

In 1947 Jackie Robinson, who was signed to the Minor League, was transferred to ML Brooklyn Dodgers, thanks to President Branch Rickey. He even won the Rookie of the Year award during his first season. 

Other players like Larry Doby and Satchel Paige soon followed Jackie in ML Baseball. 

Nevertheless, baseball history facts show that integration happened slowly because many minor leagues needed time to blend. 

Even though African-American players signed club contracts, other game levels needed integration. 

Examining the history of baseball in America, I can notice that by the 1950s, African-Americans became more frequent in MLB, and the “colored” leagues started disappearing.

The Golden Age of baseball was between 1920 and 1960 when baseball emerged as the favorite national sport in America

A unique accent can be put on the post-war boom, the ’50s, and the ’60s.


During the ’50s, the center of baseball was New York, with its teams winning the World Series consecutively from 1950 to 1956. 

Other than that, the ’50s were a decade when ML teams changed cities and relocated, a trend that continued through the 60s. 

Other notable facts from the history of baseball in America during the 50s were baseball being broadcast on TV for the first time and the progress of Little League Baseball. 

Maybe one of the most important events in the Golden Age of Baseball happened on the 3rd of October 1951. This is when Bobby Thompson hit the famous home run, known as the “Shot heard round the World.”

Besides these notable happenings in the history of baseball, it’s also interesting to know that The Yankees dominated the field during the 50s, with their mastery decreasing in the 60s.


Baseball facts further show that during the ’60s, every league in baseball expanded. 

The ’60s were a decade of low pitching too, which probably resulted in decreased attendance of the games. 

Television also played a part in this because now people could enjoy baseball from the comfort of their own homes too.

A notable event in the 60s, which I regard as worth mentioning, is the MLB single-season 61 home run record set by Roger Maris in 1961. This record wasn’t broken until 1998

The expansion era

As I noted above, baseball leagues underwent an expansion during the ’50s and the ’60s, which was the first time since 1901.

During the 1968 season, each league had ten teams, two more than before, and consequently, the schedule of the games expanded from 154 to 162

Two of the teams, winners in their leagues, met in the World Series, playing to be the next Baseball champions. 

According to facts about baseball history, the game’s format changed again in 1969, when another two teams were added to MLBs. 

The expansion influenced the schedules, which became longer, and had postseason games added. 

With all of these changes happening in two decades, this was a considerable turn-point in the history of baseball.

21st Century Baseball

The globalization of baseball

I have described the history of baseball in America as detailed as I could, and now you can comprehend why baseball is more than just a sport for the American nation. 

However, in the 21st century, baseball became more than an American national wonder and started expanding beyond the States’ borders. 

Some will say that Americans couldn’t keep baseball to themselves, yet, I believe it’s normal for a game so exciting and popular to gain recognition internationally

The World Baseball Classic

The International focus on baseball probably increased with the World Baseball Classic, the world tournament first held in 2006

To explain, the ML revealed the first World Baseball Classic in May of 2005. 

Today, the World Baseball Classic is an international baseball tournament run by MLB and MLB Player Association under the governance of the World Baseball Softball Confederation.

Advancements in baseball technology

Technology has dramatically impacted baseball, as with everything else in the modern world, and the 21st century probably brought baseball’s most influential technological advances.

Data analytics and player-tracking systems have become immensely prominent. Thanks to them, the player’s development and performance can be successfully tracked and analyzed. 

Moreover, wearable technology found its place too. Heart monitors, smartwatches and sleep monitors help track progress and health, and biomechanical advancements aid in preventing injuries.

The betting experience has been enhanced too. Widely available betting sites, statistics, and analytics give baseball admirers and bettors another level of sophisticated tools.

When discussing the future of baseball technology, I can’t miss the AI tools, which are anticipated to further revolutionize the game both on the field and out of it. 

In the last decade, technological advancements are becoming an inseparable part of baseball history, an improvement whose influence is yet to be seen and experienced. 

Baseball’s ongoing legacy

After going through everything in the history of baseball, together we can assume that American baseball has left an ongoing legacy and the country and its players and admirers have developed a legendary sport

We can see that the game underwent many changes over the centuries, while numerous famous baseball stars emerged, creating the narrative. 

Breaking the color line in baseball by Jackie Robinson revolutionized the sport. Still, besides the integration, the expansion of baseball and its becoming an international sport are important parts of baseball’s legacy.
