Conservatism is a philosophy that emerged as a reaction to liberalism in Renaissance Europe. Specifically, conservativism is a philosophy supporting monarchy and hereditary aristocracy linked to monarchy. There are very very few people in the USA who are conservatives. Instead, what the USA calls conservatives are regressive liberals and what the USA calls liberals are neoliberals and progressive liberals.
