Farmers and herders settled in the plains surrounding the Hindu Kush as early as 7000 B.C. These people may have grown rich off the lapis lazuli they found along riverbeds, which they traded to early city sites to the west, across the Iranian plateau and Mesopotamia. As farms and villages grew and thrived in Afghanistan, these ancient people eventually invented irrigation (digging ditches for water so it flows to crops) that allowed them to grow crops on the northern Afghanistan desert plains. This civilization (advanced state of organization) is today called BMAC (Bactria–Margiana Archaeological Complex), or the "Oxus civilization".
The Oxus civilization expanded as far east as western edge of the Indus Valley during the period between 2200 and 1800 B.C. These people, who were the ancestors of the Indo-Aryans, used the term "Aryan" to identify their ethnicity, culture, and religion. Scholars know this when they read the ancient texts of these people; the Avesta of Iranian people and the Vedas of Indo-Aryans.
Zoroaster, the founder of the Zoroastrian religion, the world's earliest monotheistic religion, (meaning a religion believing in one god) lived in the area (somewhere north of today's Afghanistan), around 1000 B.C.
Before the middle of the sixth century BCE, the land was held by the Medes.
Then the Achaemenids took over control of the land and made it part of the Persian empire. Alexander the great defeated and conquered the Persian Empire in 330 BCE. He founded some cities in the area. The people used Greek culture and language. After Alexander, Greco-Bactrians, Scythians, Kushans, Parthians and Sassanians ruled the area.
Kushans spread Buddhism from India in the 1st century BCE, and Buddhism remained an important religion in the area until the Islamic conquest in the 7th century CE.
The Buddhas of Bamiyan were giant statues, a reminder of Buddhism in Afghanistan. They were destroyed by the Taliban in 2001. There were international protests. The Taliban believe that the ancient statues were un-Islamic and that they had a right to destroy them.
Arabs introduced Islam in the 7th century and slowly began spreading the new religion. In the 9th and 10th centuries, many local Islamic dynasties rose to power inside Afghanistan. One of the earliest was the Tahirids, whose kingdom included Balkh and Herat; they established independence from the Abbasids in 820. The Tahirids were succeeded in about 867 by the Saffarids of Zaranj in western Afghanistan. Local princes in the north soon became feudatories of the powerful Samanids, who ruled from Bukhara. From 872 to 999, north of the Hindu Kush in Afghanistan enjoyed a golden age under Samanid rule.
In the 10th century, the local Ghaznavids turned Ghazni into their capital and firmly established Islam throughout all areas of Afghanistan, except the Kafiristan region in the northeast. Mahmud of Ghazni, a great Ghaznavid sultan, conquered the Multan and Punjab region, and carried raids into the heart of India. Mohammed bin Abdul Jabbar Utbi (Al-Utbi), a historian from the 10th century, wrote that thousands of "Afghans" were in the Ghaznavid army. The Ghaznavid dynasty was replaced by the Ghorids of Ghor in the late 12th century, who reconquered Ghaznavid territory in the name of Islam and ruled it until 1206. The Ghorid army also included ethnic Afghans.
Afghanistan was recognized as "Khorasan", meaning "land of the rising sun," which was a prosperous and independent geographic region reaching as far as the Indus River.
All the major cities of modern Afghanistan were centers of science and culture in the past. The New Persian literature arose and flourished in the area. The early Persian poets such as Rudaki were from what is now Afghanistan. Moreover, Ferdowsi, the author of Shahnameh, the national epic of Iran, and Rumi, the famous Sufi poet, were also from modern-day Afghanistan. It has produced scientists such as Avicenna, Al-Farabi, Al-Biruni, Omar Khayyám, Al-Khwarizmi, and many others who are widely known for their important contributions in areas such as mathematics, astronomy, medicine, physics, geography, and geology. It remained the cultural capital of Persia until the devastating Mongol invasion in the 13th century.
Timur, the Turkic conqueror, took over in the end of the 14th century and began to rebuild cities in this region. Timur's successors, the Timurids (1405–1507), were great patrons of learning and the arts who enriched their capital city of Herat with fine buildings. Under their rule Afghanistan enjoyed peace and prosperity.
Between south of the Hindu Kush and the Indus River (today's Pakistan) was the native land of the Afghan tribes. They called this land "Afghanistan" (meaning "land of the Afghans"). The Afghans ruled the rich northern Indian subcontinent with their capital at Delhi. From the 16th to the early 18th century, Afghanistan was disputed between the Safavids of Isfahan and the Mughals of Agra who had replaced the Lodi and Suri Afghan rulers in India. The Safavids and Mughals occasionally oppressed the native Afghans but at the same time the Afghans used each empire to punish the other. In 1709, the Hotaki Afghans rose to power and completely defeated the Persian Empire. Then they marched towards the Mughals of India and nominally defeated them with the help of the Afsharid forces under Nader Shah Afshar.
In 1747, after Nader Shah of Persia was killed, a great leader named Ahmad Shah Durrani united all the different Muslim tribes and established the Afghan Empire (Durrani Empire). He is considered the founding father of the modern state of Afghanistan while Mirwais Hotak is the grandfather of the nation.
During the 1800s, Afghanistan became a buffer zone between two powerful empires, British India and Russia. As British India advanced into Afghanistan, Russia felt threatened and expanded southward across Central Asia. To stop the Russian advance, Britain tried to make Afghanistan part of its empire but the Afghans fought wars with British-led Indians from 1839 to 1842 and from 1878 to 1880. After the third war in 1919, Afghanistan under King Amanullah gained respect and recognition as a completely independent state.
The Kingdom of Afghanistan was a constitutional monarchy established in 1926. It was the successor state to the Emirate of Afghanistan. On 27 September 1934, during the reign of Zahir Shah, the Kingdom of Afghanistan joined the League of Nations. During World War II, Afghanistan remained neutral. It pursued a diplomatic policy of non-alignment.
The creation of Pakistan in 1947 as its eastern neighbor created problems. In 1973, political crises led to the overthrow of the king. The country's new leader ended the monarchy and made Afghanistan a republic. In 1978, a Communist political party supported by the Soviet Union seized control of Afghanistan's government. This move sparked rebellions throughout the country. The government asked the Soviet Union for military assistance. The Soviets took advantage of the situation and invaded Afghanistan in December 1979.
Most people in Afghanistan opposed the sudden Soviet presence in their country. For nearly a decade, anti-Communist Islamic forces known as "Mujahideen" were trained inside neighboring Pakistan to fight the Soviets and the Afghan government. The United States and other anti-Soviet countries supported the Mujahideen. In the long war, over one million Afghan civilians were killed. The Soviet Army also lost more than 15,000 soldiers in that war. Millions of Afghans left their country to stay safe in neighboring Pakistan and Iran. In 1989 the Soviet Army withdrew the last of its troops.
