Oh come on, don't make others write an entire essay for you.
I'll give you some ideas though!
Think of a world where supercomputers have blackmailed humanity by threatening nuclear war if there's no obedience
Think of a world where robots are so developed, the police/FBI/CIA use them to spy on each and every person
Think of a world where technology is so developed, we've trashed the environment and everything is dystopian and disgusting.
Best of luck!
This is true. Many kings would plan and carry out invasions to gain goods, land and other loot and to expand their rule because many of them worried that another power would get too strong and take over their kingdom, and every king wanted to avoid that because they had become very fond of being king.
