MPs have voted to ban fox hunting with dogs by a majority of 356 to 166.
The ban won't become law until it's passed by the House of Lords. MPs also have to discuss when the ban will come in, as some people want to delay it.
But many people are more worried by the fact that pro-hunt protestors broke into the House of Commons while the politicians were discussing the ban.
Five people ran into the Commons chamber and held up the debate by 20 minutes while they were dealt with.
It was the second time protesters have broken into the Commons in recent months, after flour was thrown at Tony Blair by a fathers' rights group
