In 2010, Kenya had a special vote where people got to decide if they wanted to change their country's constitution. This is like the rule book that says how the country should be run and what people's rights are. By voting in this referendum, people were deciding if they wanted to change some of the rules in this rule book.
The reason for this vote was because things had not been going very well in Kenya. In the past, there had been a lot of fighting between different groups of people. Some people wanted to change the constitution so that everyone could have equal rights and fewer people would get hurt.
Before the vote, people talked about what they liked and didn't like about the constitution. They talked about things like how powerful the president should be, how much land people should be allowed to own, and how much power the different parts of the government should have. These are all important things that can affect how a country runs.
On the day of the vote, people went to special places called polling stations. They were given a piece of paper where they could say "yes" or "no" to changing the constitution. After that, all the votes were counted to see what most people wanted.
In the end, most people said "yes" to changing the constitution. This meant that the rule book for how Kenya was run was going to be updated. The changes that were made were supposed to make the country better and safer for everyone who lives there.
