Afghan Independence Day
Afghan Independence Day is celebrated as a national holiday in Afghanistan on 19 August to commemorate the Anglo-Afghan Treaty of 1919 and relinquishment from British Protected state status. The treaty granted a complete neutral relation between Afghanistan and Britain. Afghanistan had become a British protectorate after the Treaty of Gandamak was signed (1879) in the Second Anglo-Afghan War. Background 
The First Anglo-Afghan War (1839–42) led to the British force taking and occupying Kabul. After this, due to strategic errors by Elphinstone, the British force was annihilated by Afghan forces under the command of Akbar Khan somewhere at the Kabul–Jalalabad Road, near the city of Jalalabad. After this defeat, the British-Indian forces returned to Afghanistan on a special mission to rescue their prisoners of war (POWs) and then withdrew. The British returned later in the Second Anglo-Afghan War. The Second Anglo-Afghan War (1878–80) first led to a British defeat at Maiwand followed by their victory at the Battle of Kandahar, which led to Abdur Rahman Khan becoming the new emir and the start of friendly British-Afghan relations. The British were given control of Afghanistan's foreign affairs in exchange for protection against the Russians and Persians. The Third Anglo-Afghan War in 1919 led the British to give up control of Afghanistan's foreign affairs finally in 1921. Observances
