What is Treaty of Lisbon (2009)?

The Treaty of Lisbon is like a new rulebook that helps friends work together better when they're playing a game.

Imagine you and your friends are in a big group, and you all want to play the same game, but some rules are getting confusing. That's what happened with some countries in Europe, they wanted to make it easier for everyone to talk and decide things together. So, in 2009, they signed the Treaty of Lisbon, which is like agreeing on a new set of simple rules.

Before the Treaty of Lisbon, some decisions needed almost everyone to agree, it was like needing all your friends to say "yes" before you could start playing. Now, with this treaty, most decisions only need about two-thirds of the group to agree, that’s like needing just a few more friends to say “yes” instead of almost all of them.

The Treaty of Lisbon also helped add new friends (countries) to the game and made it easier for people in Europe to talk about things like money, jobs, and school. It’s like having a bigger group with clearer rules, everyone can play better together!
