Onjo was a very important leader in ancient Korea. He was the first king of a kingdom called Paekche.

Some stories say he was the son of King Dongmyeong. Dongmyeong was the man who started the Goguryeo kingdom in the north. Onjo had a brother named Biryu. The two brothers moved south to find their own lands to rule. They wanted to find a place where they could be safe and strong. This move helped start a new way of life for many people.

Building a new kingdom was a big job for Onjo. He and his brother traveled with many followers to the south. Biryu tried to start a small state in a place called Michuhol. However, his state did not stay strong for very long. After Biryu died, his people joined Onjo instead. Onjo then gave his new land the name Paekche.

This was the start of a famous royal family.

Onjo had to be a brave leader to protect his people. The Malgal tribes attacked from the north in 13 BC and 8 BC. Onjo led his own armies to fight these invaders. He won both times and kept his people safe.

To make the kingdom even safer, he moved the capital city. In 5 BC, he moved it south of the Han River. He named this new capital Hanam Wiryeseong. This location was much easier to defend against enemies.

Onjo also worked to grow his kingdom's borders. In 8 AD, he moved his armies to take over the Mahan lands. He was very clever and told people he was only going hunting.

This plan helped him conquer almost all of Mahan. When he won, he showed great kindness to the people. The Mahan King had asked Onjo to treat his people with mercy. Onjo respected this request and took the people in. He even stopped a rebellion in 16 AD with 5,000 soldiers.

Onjo ruled for 46 years before he died in 28 AD. He died of natural causes during his long reign.

His eldest son, Daru, became the next king after him. Onjo did more than just start a kingdom. He laid the foundation for a dynasty that lasted a very long time. His family ruled for 678 years. They had 31 different rulers throughout that history. His work changed the map of Korea forever.
