Major political parties in the world cover with their programme all aspects of everyday-life. Even if it is not possible, they provide some guidances.
Because people have different political opinions, also parties do have, and they are divided in some ways.
Left or leftists is a party that desires and backs anything that is considered a progress. They want to change major aspects of life. In general (but not always) the left parties were religion-sceptic, republican (as opposed to monarchy), socialistic, promoting ecology, women's suffrage etc.
Right party is usually conservative, that desires status quo and accepting progress, but wanting it to go its own way. In general these parties are religious, monarchistic (as opposed to republic), libertarian, nationalistic etc.
The hawks is a party or group of people that promotes declaring or joining a war. They are opposition of doves who do anything to keep peace.
In democracies many parties are allowed, in totalitarian states only one is, and other are illegal.
