Alexander the Great vs Ibn Tumart

Alexander led his Macedonian army across the Hellespont into Asia Minor and defeated a Persian force under local satraps at the Granicus River. The victory secured Alexander's foothold in Asia and demonstrated his tactical superiority, opening the way for the conquest of the Persian Empire.

Alexander's army defeated the Persian king Darius III at Issus in Cilicia. Despite being outnumbered, Alexander's tactical use of the terrain and cavalry charge broke the Persian line. Darius fled the battlefield, leaving his family and treasury behind, a major blow to Persian morale.

Alexander besieged the island city of Tyre for seven months, constructing a causeway to breach its walls. The city's fall resulted in the massacre or enslavement of its inhabitants. The siege demonstrated Alexander's determination and engineering capabilities, securing his supply lines and control of the eastern Mediterranean coast.

Alexander faced Darius III at Gaugamela in Mesopotamia with a massive Persian army. Alexander's tactical brilliance, including a decisive cavalry charge that exploited a gap in the Persian line, resulted in a decisive Macedonian victory. Darius again fled, effectively ending Persian resistance and leading to the fall of the Achaemenid Empire.

Alexander founded the city of Alexandria on the Mediterranean coast of Egypt. He personally selected the site and oversaw the initial planning. Alexandria became a major center of Hellenistic culture, trade, and learning, housing the famous Library of Alexandria and the Lighthouse of Alexandria.

Alexander crossed the Indus River and defeated King Porus at the Battle of the Hydaspes. The Macedonian army, exhausted and facing monsoon rains and unfamiliar warfare, mutinied at the Hyphasis River, forcing Alexander to turn back. This campaign marked the easternmost extent of his conquests.

Ibn Tumart proclaimed himself the Mahdi, the guided one, after returning from the East. He began preaching a strict reformist message, condemning the Almoravids for their perceived religious laxity and calling for a return to the Quran and Sunnah.

Ibn Tumart founded the Almohad movement (al-Muwahhidun) in the Atlas Mountains of Morocco. He organized his followers into a disciplined religious and military community, rejecting the Almoravid interpretation of Islam and advocating for tawhid (strict monotheism).

Ibn Tumart compiled his teachings into a book titled 'A'azz ma Yutlab' (The Most Precious of What is Sought). This work outlined the Almohad doctrine, emphasizing the unity of God and rejecting anthropomorphism, and became the foundation of the movement's ideology.

Ibn Tumart's Almohad forces were defeated by the Almoravids at the Battle of al-Buhayra near Marrakech. This setback prevented the Almohads from capturing the Almoravid capital and forced them to retreat to the mountains.

Ibn Tumart died shortly after the Battle of al-Buhayra, possibly from wounds or illness. His death was kept secret by his successor Abd al-Mu'min, who continued the Almohad movement and eventually overthrew the Almoravids.
