After Islam was spread in Iran during the government of Sultan Mahmood Ghaznavi, and after his army's attack on India, Islam entered this large land along with Persian language and Sufism. With the passage of time, Muslim, and sometimes Iranian, governments were formed, as a result of which the Persian language was spread in the Indian Subcontinent, so extensively that it became the language of religion, politics, culture, literature, and art for centuries.
