secular country is a country where no religion is imposed by, or sponsored by the state. Where people are free to practice any religion or no religion and it does not affect how they are valued and treated as citizens, where there could be no persecution based on your religion or lack thereof. Where the government can create no law to imposed any religion-based rule on the citizens.
