I: INTRODUCTION
Afghanistan, officially Transitional Islamic State of Afghanistan, republic in southwestern Asia, bounded on the north by Turkmenistan, Uzbekistan, and Tajikistan; on the east by China and the part of the disputed territory of Jammu and Kashmīr controlled by Pakistan; on the south by Pakistan; and on the west by Iran. Afghanistan lies across ancient trade and invasion routes from Central Asia into India. This position has been the greatest influence on its history because the invaders often settled there. Today the population includes many different ethnic groups. Most of the present borders of the country were drawn up in the 19th century, when Afghanistan became a buffer state, or neutral zone, between Russia and British India. Kābul is the capital and largest city.
