When it comes to studying history, it can get boring from time to time. Nobody loves memorizing different dates or complicated names of people who have not been alive for centuries. On the other hand, history is fascinating to study. Learning about what happened in the past can certainly be fun, mainly about significant occurrences that had a big impact on our lives.

Unfortunately, history does not always treat everything equally. Depending on their significance and scale, some parts are often mentioned more and are given more meaning. Some events were rewritten; others were merely forgotten.

Below, you can find three exciting but forgotten historical events you never knew about.

Forgotten Wars - The Mexican-American War

When it comes to wars of the 18th century, many will come to mind. A series of battles were fought in Europe. For example, the Napoleonic Wars transformed the whole continent and shifted the balance of power.

There was the American Civil War on the other side of the ocean, and it is a well-recorded and critical event in world history.

However, alongside these and other major wars, there is one that is often overlooked by everyone, despite its irrefutable importance. That is, of course, the Mexican-American War, fought in the 1840s between the two nations. This war is undoubtedly one of the most important forgotten historical events for several reasons.

The 18th century was a time when the two countries were still trying to find their identities. North America still was not fully colonized, and the United States was trying to expand westwards. It believed that stretching the country from coast to coast was its "manifest destiny."

On the other hand, Mexico was in a much more challenging situation. It had just achieved independence from the Spanish Empire and struggled to keep its territories together.

The two countries went to war over the territory of Texas, which was initially under Mexican control but had broken away in the 1830s during the Texas Revolution. Most of the people in Texas were American immigrants that wanted to join the US after the revolution and applied for state membership.

Due to the border disputes between Mexico and the US, the countries fought a two-year-long war that ended in a decisive US victory. Mexico lost a third of its territory, including the modern-day US southwest, while the United States strengthened its dominant power.

But why is the Mexican-American war considered one of the forgotten historical events? It was, without a doubt, crucial and influenced the next twenty years. Unfortunately, it would be overshadowed by the American Civil War.

Perhaps history would have been different without one of the most forgotten historical events - the war between Mexico and the US. The Civil War is a more "iconic" event in world history due to the unique narrative and scale of the stakes that existed. Yet, the Civil War was a direct consequence of the Mexican-American War.

Unexplained & Forgotten Historical Events - The Tunguska Incident

This one is for those who love hard-to-explain, strange events, and conspiracy theories.

In the morning of June 30, 1908, the residents of the sparsely populated Eastern Siberia region, near the Tunguska River in Russia, heard the noise of a massive explosion. They reported that they did not see anything, but the impact of the incident was so significant that it was felt worldwide.

Abnormal seismic activity was observed in countries like the US and the UK. Atmospheric pressure changes were detected throughout the continent. However, nobody could explain what caused the anomalies.

Later, however, a blast site was found. About 800 miles of forest in Eastern Siberia was utterly destroyed - reduced to atoms. But there was no crater, so the scientists excluded the option of a meteor hitting the surface. The explosion is thought to have released about 15 megatons of energy, which would have been deadly enough to wipe out a big city. In fact, due to the insanely large scale of the impact, the Tunguska Incident is one of the most interesting forgotten historical events.

To this day, scientists have failed to agree on one explanation. The most prevalent version states that the explosion resulted from an airburst of a meteor. We are lucky that the meteor could not hit the surface if this theory is accurate since it would have had much deadlier results. It would have the potential of causing big earthquakes and tidal waves in Asia.

While some conspiracy theorists have claimed a potential alien visit or a concealed bomb experiment, it is easy to understand why their thoughts have been dismissed.

Due to the difficulty of explaining it, the Tunguska incident remains one of the mysterious, forgotten historical events.

Forgotten Historical Events That Changed Our Everyday Lives -The Gregorian Calendar

Nowadays, we do not think about many details of our life and take them for granted. We don't think about how they were created and developed to achieve the form we consume them every day. One of those objects is the calendar.

While it is just an ordinary object at first glance, the story of how the modern calendar came to be is, surprisingly, one of the most forgotten historical events.

The calendar that most of the world uses now is called the Gregorian Calendar - after Pope Gregory XIII. With the Pope's initiation in 1582, the calendar was changed to reflect the day and night cycle more accurately and how many days there were in a year.

The main reason behind the change was that the Julian Calendar that was in use before the change incorrectly assumed that a year had 365.25 days. Thus, every fourth year was a leap year.

The change came about due to the mistakes regarding the equinoxes. The equinoxes are the times of the year when day and night are the same lengths. Because of the small error in the Julian Calendar, the total time added up had caused the actual equinox not to be on March 21. In fact, it occurred days before its expected date.

The Gregorian Calendar corrected this inaccuracy and produced the calendar that we use today. It even shifted the date by ten days. So, Europeans woke up on Friday, October 15, after they had gone to sleep on Thursday, October 4. The whole story is one of the most unique but forgotten historical events to date.

So, what other forgotten historical events do you think everyone should know?
