The Bangladesh Liberation War, fought between Pakistan and Bangladesh (formerly East Pakistan), resulted in the secession of Bangladesh.

Pakistan, a country located in South Asia, has a rich and complex history that spans over 7,000 years. The region has been home to some of the world's oldest civilizations, including the Indus Valley Civilization, which dates back to around 3300 BCE. The country has been ruled by various empires, dynasties, and governments, shaping its culture, politics, and economy.

In the 6th century BCE, the Persian Empire, under the rule of Cyrus the Great, conquered the region. Later, Alexander the Great (356 BCE - 323 BCE) invaded the region in 326 BCE, leaving a lasting legacy of Greek culture and architecture.

General Ayub Khan seized power in 1958 CE, marking the beginning of martial law and dictatorship in Pakistan. His rule was characterized by significant economic growth, but also human rights abuses and political repression.

The Indus Valley Civilization, one of the world's oldest urban civilizations, flourished in the region now known as Pakistan. The civilization was known for its sophisticated urban planning, architecture, and water management systems. The Vedic period (1500 BCE - 500 BCE) saw the rise of Hinduism and the composition of the Vedas, ancient Hindu scriptures.

The Arab conquest of Sindh in 712 CE marked the beginning of Islamic rule in the region. The Ghaznavid Empire (963 CE - 1186 CE), under the rule of Mahmud of Ghazni, played a significant role in spreading Islam throughout the region. The Mughal Empire (1526 CE - 1857 CE), founded by Babur, a Central Asian ruler, brought stability and cultural advancements to the region.

Pakistan faced significant challenges in its early years, including refugee crises, economic instability, and conflicts with neighboring India. The country was ruled by a parliamentary system, with Liaqat Ali Khan as its first Prime Minister.
