Trajan was a Roman ruler who was known for his exceptional military abilities and his philanthropic work during his reign from 98 AD to 117 AD. He was honored with the title of “Optimus Princeps,” or “the best ruler,” by the Senate. He was born in Italica, Spain, to a nobleman father. Marcus Cocceius Nerva ruled the vast empire in 96 AD. However, he was highly unpopular with the common public and the court officials. Without any child to succeed him, he was compelled to choose Trajan as his successor. When Trajan ascended the throne, the kingdom prospered with the construction of several establishments that proved to be a boon for the common public. Moreover, his military campaigns contributed to his celebrity status. He conquered the Dacians and launched three military invasions. Thus, under his reign, the Roman Empire reached its peak. Trajan performed many other social and political reforms that made him popular in his rival kingdoms, too. After a successful reign that lasted for 19 years, Trajan died due to an unknown illness. His adopted son, Hadrian, succeeded him.
