Analysis of information sources in references of the Wikipedia article "ज़िम्मी" in Hindi language version.
A Dhimmi is a non-Muslim subject of a state governed in accordance to sharia law. The term connotes an obligation of the state to protect the individual, including the individual's life, property, and freedom of religion and worship, and required loyalty to the empire, and a poll tax known as the jizya, which complemented the Islamic tax paid by the Muslim subjects, called Zakat.
According to the dhimma status system, non-Muslims must pay a poll tax in return for Muslim protection and the privilege of living in Muslim territory. Per this system, non-Muslims are exempt from military service, but they are excluded from occupying high positions that involve dealing with high state interests, like being the president or prime minister of the country. In Islamic history, non-Muslims did occupy high positions, especially in matters that related to fiscal policies or tax collection.
