Augustus was a man who lived a long time ago, kind of like how your grandma and grandpa are really old. He was the leader of a big group of people called the Romans, who were very good at fighting and building things.
Augustus had a plan for how to treat the places that were very far away from where he lived, like a different part of the playground that you don't go to very often. This was called his eastern policy.
One of the things Augustus did was make friends with some people who lived far away in a place called Parthia. It's kind of like if you have a new friend at school who lives in a different town. Augustus wanted to be friends with Parthia because they had a lot of good things like gold and spices. They could also make trouble for the Romans if they were mad.
Another thing Augustus did was pick certain people to go to these far-away places and be in charge. These people were called governors. It's like if you had a babysitter who watched you when your parents went out, except the governor had to run the whole place.
Augustus also made sure that the Roman soldiers who went to these far-away places were treated well. He wanted them to be happy and strong so they could protect the Romans if anything bad happened.
Overall, Augustus' eastern policy was about making new friends, picking good people to take care of far-away places, and making sure the soldiers were happy and strong.
