If we take your argument right, than how Ghauri is a Sultan of Pakistan? He was a simple invader from Afghanistan that looted and destroyed the region we know as present day Pakistan.... It is like Sparta naming its weapons after Xerxes.
Early life
Mu'izz was born in 1149 in the Ghor region of what is now present day Afghanistan. The exact date of his birth is unknown. His father,
Baha al-Din Sam I, was the local ruler of the Ghor region at the time.
[1] Mu'izz also had an elder brother named
Ghiyath al-Din Muhammad. During their early life, Mu'izz and Ghiyath were imprisoned by their uncle
Ala al-Din Husayn, but were later released by the latter's son
Sayf al-Din Muhammad.
[3] When Sayf died in 1163, the Ghurid nobles supported Ghiyath, and helped him ascend the throne. Ghiyath shortly gave Mu'izz control over Istiyan and Kajuran. However, the throne was challenged by several Ghurid chiefs; Mu'izz aided Ghiyath in defeating and killing a rival Ghurid chief named Abu'l Abbas.
Early campaigns
Ghiyath was then challenged by his uncle Fakhr al-Din Masud, who claimed the throne for himself, and had allied with Tadj al-Din Yildiz, the
Seljuq governor of
Herat, and
Balkh.
[4] However, the coalition was defeated by Ghiyath and Mu'izz at Ragh-i Zar. The brothers managed to kill the Seljuq governor during the battle, and then conquered
Zamindawar,
Badghis,
Gharchistan, and
Guzgan. Ghiyath, however, spared Fakhr al-Din and restored him as the ruler of
Bamiyan. Mu'izz, after returning from an expedition from Sistan, was shortly awarded with
Kandahar by his brother. In 1173, the two brothers invaded
Ghazni, and defeated the
Oghuz Turks who had captured the city from the
Ghaznavids. Mu'izz was then appointed as the ruler of Ghazni.
[4][5]
In 1175, the two brothers conquered
Herat from its Seljuq governor, Baha al-Din Toghril, and also managed to conquer Pushang. The ruler of
Sistan, Taj al-Din Harb ibn Muhammad, shortly acknowledged the sovereignty of the Ghurids, and so did the
Oghuz Turks dominating
Kirman.
[6]
During the same period, the
Khwarazmian Sultan Shah, who was expelled from
Khwarezm by his brother
Tekish, took refuge in Ghor and requested military aid from Ghiyath. Ghiyath, however, did not help the latter. Sultan Shah managed to get help from the
Kara-Khitan Khanate, and began plundering the northern Ghurid domains.
Invasion of India
After having helped his brother in expanding the western frontiers of the Ghurid Empire, he began to focus on India. He shortly invaded India, first capturing Multan from a fellow the Qarmatians in 1175–76. He then shortly captured Uch. Three years later he invaded Gujarat and was roundly defeated by the Hindu Queen Naikidevi. However, Mu'izz was able to take Peshawar and Sialkot. In 1186, Mu'izz, along with Ghiyath, ended the Ghaznavid dynasty after having captured Lahore and executed the Ghaznavid ruler Khusrau-Malik.
