According to the Merriam Webster Dictionary, an empire is “a major political unit having a territory of great extent or a number of territories or peoples under a single sovereign authority”. It comes from the Latin word imperium, meaning «“authority over family members and slaves exercised by the head of a household, supreme administrative authority, dominion, power exercised by a Roman emperor”, from imperāre “to give orders, exercise authority, hold political power” + -ium, deverbal suffix of function or state».

The Roman Empire was the second empire to exist in the world (the first was the Akkadian Empire), but it was one of the most effective. Starting as a Republic (from the Latin res publica, literally meaning “the thing of the people”), Rome was an independent city-state founded on top of a hill.

Battles with the neighbours were frequent. Julius Caesar, with his immeasurable ambition, became a member of the senate and an army commander, conquering many lands for the Republic. One day, he returned to Rome, but decided to take a legion with him, which was forbidden. The Rubicon River bounded the Italian domains within the Empire. Those who crossed it commanding an army were considered traitors and were sentenced to death. Julius Caesar knew this and he knew he could not go back on his decision after crossing the river. And so, the expression “crossing the Rubicon” (meaning “passing the point of no return”) was born. Julius Caesar crossed the river and civil war began. He took power and became a dictator. He was a dictator only for a few days… until he was murdered.

After some turbulent times, Gaius Octavius, the adoptive son of Julius Caesar, took the power and became the sole ruler of the Roman Empire. He named himself as Augustus, the Latin word for “majestic” or “great”. He also adopted his father’s name, Caesar. From then on, although it was not written as law, it became tradition for sons to succeed their fathers and be named as Caesar, like the “founder”. This denomination stuck and evolved to “czar” in Russia.

However, this was not the only legacy they left us. Buildings, roads, bridges are still there to be admired or used throughout Europe, Middle East, and North Africa. Many languages evolved from Latin, like French, Spanish, Italian, and Portuguese, and there are still Latin expressions in use (like status quo, alter ego, de jure, per capita, and vice versa, among many others). And speaking about Latin expressions, the law is full of them, partly because the current juridical system was based on the Roman one. Of course, we must not forget that the official names of plants and animals are also in Latin.

The Roman Empire, as such, ended in the 4th century. Since then, many other empires were born and died. Together with tales of grandeur, there are tales of atrocities and attempts to annihilate other cultures. For better or worse, empires change the territories they govern, but their end is certain.
