He went on to star in some successful Hindi films of those times, such as Saajan (1991), Hum Aapke Hain Koun..! (1994), Karan Arjun (1995), Judwaa (1997), Pyar Kiya To Darna Kya (1998) and Biwi No.1 (1999), having appeared in the highest earning films of seven separate years during his career.

In 1999, Khan won a Filmfare Award for Best Supporting Actor for his extended appearance in Kuch Kuch Hota Hai (1998), and since then has starred in several critical and commercial successes, including Hum Dil De Chuke Sanam (1999), Tere Naam (2003), Mujhse Shaadi Karogi (2004), No Entry (2005), Partner (2007), Wanted (2009), Dabangg (2010), Ready (2011) and Bodyguard (2011), which has become the second highest-grossing Bollywood film of all-time. Khan has thus established himself as one of the most successful actors of Hindi cinema.

World War I (WWI), which was predominantly called the World War or the Great War from its occurrence until 1939 (World War II), and the First World War or World War I thereafter, was a major war centred in Europe that began on 28 July 1914 and lasted until 11 November 1918. It involved all the world's great powers, which were assembled in two opposing alliances: the Allies (based on the Triple Entente of the United Kingdom, France and Russia) and the Central Powers (originally centred around the Triple Alliance of Germany, Austria-Hungary and Italy; but, as Austria–Hungary had taken the offensive against the agreement, Italy did not enter into the war). These alliances both reorganised (Italy fought for the Allies), and expanded as more nations entered the war. Ultimately more than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. More than 9 million combatants were killed, largely because of enormous increases in lethality of weapons, thanks to new technology, without corresponding improvements in protection or mobility. It was the sixth-deadliest conflict in world history, subsequently paving the way for various political changes such as revolutions in the nations involved.
