What is the fiddler on the roof about?

Basic Overview unlike what is stated above. Tevye and his family are living happily. Until some boys want to marry his daughters. Tevye wanted his daughter to marry lazorwolf, but she did no want to. Instead she picked her own mate. TOTALLY against how they were raised. The daughters were rebellious and wanted change. In the end, the russians take over the place and ruin his daughters wedding. Both of his daughters get married. Two still remain. They have to live Anatevka (where they always lived) and moved to another country. Also very religious folks. Had a Rabbi they talked to a lot.
