Islamic conquest of Afghanistan in the context of "Arab Muslims"

The ancient history of Afghanistan, also referred to as the pre-Islamic period of Afghanistan, dates back to the prehistoric era and the Helmand civilization around 3300–2350 B.C. Archaeological exploration began in Afghanistan in earnest after World War II and proceeded until the late 1970s during the Soviet–Afghan War. Archaeologists and historians suggest that humans were living in Afghanistan at least 50,000 years ago, and that farming communities of the region were among the earliest in the world. Urbanized culture has existed in the land from between 3000 and 2000 BC. Artifacts typical of the Paleolithic, Mesolithic, Neolithic, Bronze, and Iron ages have been found inside Afghanistan.

After the Indus Valley Civilisation stretched up to northeast Afghanistan, it was inhabited by the Iranic tribes and controlled by the Medes until about 500 BC when Darius the Great (Darius I) marched with his Persian army to make it part of the Achaemenid Empire. In 330 BC, Alexander the Great of Macedonia invaded the land after defeating Darius III of Persia in the Battle of Gaugamela. Much of Afghanistan became part of the Seleucid Empire followed by the Greco-Bactrian Kingdom. Seleucus I Nicator was defeated by Chandragupta Maurya and gave his daughter in a peace treaty. The land was inhabited by various tribes and ruled by many different kingdoms for the next two millennia. Before the arrival of Islam in the 7th century, there were a number of religions practiced in modern-day Afghanistan. Zoroastrianism and Ancient Iranian religions were practiced in western Afganistan (Khorasan and Herat). Hinduism and Buddhism was primarily practiced in regions of Eastern (Kabul) and South-Eastern Afganistan (Kandahar). The Kafiristan (present-day Nuristan) region, in the Hindu Kush mountain range, was not converted until the 19th century. They still follow the ancient Vedic religion (related to modern day Hinduism).

The history of Arabs in Afghanistan spans over one millennium since the 7th century beginning with the Islamic expansion all the way until the early 20th century. The Ethnic Arabs of Afghanistan are an ethnic minority making up 1-2% of the country's population. They speak a distinct dialect of Arabic called Central Asian Arabic along with either Dari (Persian) or Pashto. Most of the early Arab communities in Afghanistan gradually lost their native language. However, a number of villages commonly referred to as Qaryeh-ye ʿArabhā (“villages of Arabs”) continue to preserve Arabic as a spoken language. Within these communities, traditional dress, cultural practices, and other markers of Arab heritage have also been retained. In recent years, renewed efforts have emerged to safeguard not only the Arabic language but also the broader Arab identity in Afghanistan, particularly under the current government, reflecting an increased recognition of the cultural and historical significance of this minority population.

Afghan Arabs are still considered a recognisable distinct ethnic group according to the Constitution of Afghanistan. Afghans who carry titles and surnames such as Sayyid, Hashimi, Quraishi, and Tamimi are usually of Arab descent.

Hinduism in Afghanistan is practiced by a very small minority of Afghans, about 30–40 individuals as of 2021, who live mostly in the cities of Kabul and Jalalabad. Afghan Hindus are ethnically Pashtun, Hindkowan (Hindki), Punjabi, or Sindhi and primarily speak Dari, Pashto, Hindko, Punjabi, Sindhi, and Hindustani (Hindi-Urdu).

Before the Islamic conquest of Afghanistan, the Afghan people were multi-religious. Religious persecution, discrimination, and religious conversions of Hindus in Afghanistan perpetrated by Muslims, has caused the Afghan Hindus, along with Buddhist and Sikh population, to dwindle from Afghanistan.

Ghazni, historically known as Ghaznayn or Ghazna, also transliterated as Ghuznee, and anciently known as Alexandria in Opiana, is a city in southeastern Afghanistan with a population of around 190,000 people. The city is strategically located along Highway 1, which follows the path that has served as the main road between Kabul and Kandahar for thousands of years. Situated on a plateau at 2,219 metres (7,280 ft) above sea level, the city is 150 kilometres (93 mi) south of Kabul and is the capital of Ghazni Province. The name Ghazni derives from the Persian word ganj, meaning "treasure."

Ghazni Citadel, the Minarets of Ghazni, the Palace of Sultan Mas'ud III, and several other cultural heritage sites have brought travelers and archeologists to the city for centuries. During the pre-Islamic period, the area was inhabited by various tribes who practiced different religions including Zoroastrianism, Buddhism and Hinduism. Arab Muslims introduced Islam to Ghazni in the 7th century and were followed in the 9th century by the Saffarids. Sabuktigin made Ghazni the capital of the Ghaznavid Empire in the 10th century. The city was destroyed by one of the Ghurid rulers but later rebuilt. It fell to several regional powers, including the Timurids and the Delhi Sultanate until it became part of the Hotaki dynasty, which was followed by the Durrani Empire or modern Afghanistan. During the First Anglo-Afghan War in the 19th century, the fortifications of Ghazni were partially demolished by British Indian forces.

Sunni Islam (Hanafi/Deobandi) is the largest and the state religion of the Islamic Emirate of Afghanistan. Islam in Afghanistan began to be practiced after the Arab Islamic conquest of Afghanistan from the 7th to the 10th centuries, with the last holdouts to conversion submitting in the late 19th century. It was generally accepted by local communities as a replacement of Zoroastrianism and Buddhism, local tribes began converting to the new religion. Islam is the official state religion of Afghanistan, with approximately 99.7% of the Afghan population being Muslim. Roughly 85% practice Sunni Islam, while around 10% are Shias. Most Shias belong to the Twelver branch and only a smaller number follow Ismailism.

After the Islamic conquest of Persia was completed, the Muslim Arabs then began to move towards the lands east of Persia and in 652 captured Herat. By the end of the 10th century CE the Turkic Ghaznavids subdued Kabul Shahi kings.
