How do different cultures show importance in their religious beliefs?

There is a wide variety of ways in which a culture can demonstrate their religious beliefs.  At the far right of the spectrum are cultures in which the religious leaders also act as the political leaders.  This is known as a theocracy and an example would be modern-day Iran.  In this country, the religious law heavily dictates how people are expected to behave on a daily basis.  While most cultures are not this extreme, the legal codes of most cultures are also still heavily influenced by religion.  

A culture can also demonstrate its religion by the festivals and holidays that are celebrated throughout the year.  In some cases, these days will be periods of time when school, business, and government offices are closed.  

Another example of religion influencing culture can be seen in India where the caste system is closely tied to Hinduism and affects social class groupings.
