Dear student, The government has abolished certain customs and practises as they are harmful for the people and the society at large. For example, it has abolished the practise of dowry system. Every year many girls or brides face harassment, violence and exploitation for dowry demands.
Some city states were monarchies ruled by kings or tyrants. Others were oligarchies ruled by a few powerful men on councils. The city of Athens invented the government of democracy and was ruled by the people for many years.
