Democracy promotion means trying to make a country be more like a democracy. This means that the people who live in that country have more power to vote and choose their leaders. Everyone gets to vote and decide together who would be the best leader for them.
But not all countries have democracy. Some countries have just one person who makes all the decisions, like a king or a queen. Or maybe there are only a few people who get to make the big decisions.
Many countries want to be more like democracies. People who support democracy promotion help countries learn how to vote and how to make everyone's voice heard. They might also help countries create more fair and open elections, where everyone gets an equal chance to vote.
The idea behind democracy promotion is that when everyone has a say in the government, the decisions made will be better for everyone. People are happier and more productive when they feel like they have a say in the things that affect their lives. And countries that are more democratic tend to be more stable and peaceful.
