Simply put, the western representative system was founded by Britain. /kloc-after the glorious revolution in Britain in the 0/7th century, British aristocrats and other classes restricted the royal power for their own power, promulgated the Bill of Rights and established the representative system. Then the industrial revolution in Britain popularized this system.

Playing the same role is democracy. From the role of decentralization, it can be said that people's democratic rights have been guaranteed. It eases social contradictions and helps to concentrate people's wisdom and so on. The disadvantage is low efficiency.

I hope it works for you.
