Akbar I was the third Mughal Emperor, who greatly expanded the empire's territory to include most of the Indian subcontinent. He is best known for his policy of religious tolerance, a radical departure for the time. Akbar abolished the 'jizya' tax on non-Muslims and invited scholars from various faiths—including Hindus, Christians, and Jains—to engage in theological debates at his 'Ibadat Khana' (House of Worship). He even attempted to create a syncretic religion called 'Din-i Ilahi,' blending elements of several faiths. Akbar was also a brilliant administrator, establishing a centralized government and a fair land-revenue system. Despite being illiterate, he was an avid patron of art, literature, and architecture, amassing a library of over 24,000 volumes. His reign is considered a golden age of Indo-Islamic culture, leaving behind architectural wonders like the city of Fatehpur Sikri.
