Let's examine the options to determine the correct association for Lala Har Dayal.

Detailed Analysis of Organisations and Lala Har Dayal

Lala Har Dayal was a key figure in establishing a revolutionary organisation in the United States.

• Ghadar Party: This was a revolutionary organisation formed by Punjabi Sikhs in the United States and Canada with the aim to overthrow British rule in India. It was founded in 1913. Lala Har Dayal played a crucial role in its formation and served as its first secretary. He was a leading intellectual and influential voice within the party, contributing significantly to its newspaper, "Ghadar." His philosophical and political ideas heavily influenced the Ghadar movement.
• Indian Independence League: This name has been associated with several political organisations formed outside India to promote Indian nationalism and independence. One prominent Indian Independence League was founded by Rash Behari Bose in Japan during World War II, which was later led by Subhas Chandra Bose. While many nationalists were part of various such leagues, Lala Har Dayal is primarily known for his leadership role in the Ghadar Party.
• Indian Home Rule Society: This organisation was founded by Shyamji Krishna Varma in London in 1905. Its aim was to promote the cause of Indian self-rule (Home Rule) through peaceful means initially, though it also supported revolutionary activities. While Lala Har Dayal was active in London around that time and associated with Shyamji Krishna Varma and India House, the primary organisation he is most strongly and famously associated with as a leader is the Ghadar Party.
• Swaraj Party: Also known as the Congress-Khilafat Swarajya Party, this party was formed in India in 1923 by leaders like Chittaranjan Das and Motilal Nehru. It worked within the framework of the Indian National Congress and advocated for contesting legislative council elections. Lala Har Dayal was not associated with the Swaraj Party, which operated much later and focused on a different political strategy within India.

Based on historical facts, Lala Har Dayal's most significant and direct association as a founder and leader was with the Ghadar Party.

Conclusion

Considering the prominent roles Lala Har Dayal played in various nationalist organisations, his association with the Ghadar Party stands out as the most significant. He was instrumental in its founding and intellectual leadership.

Therefore, the correct option is the Ghadar Party.

Additional Information: The Ghadar Movement

The Ghadar Party was formed by Indian immigrants, mostly from Punjab, in the early 20th century, primarily in the Pacific Coast of the United States and Canada. The term "Ghadar" itself means "rebellion" or "mutiny." The party's main objective was to launch an armed rebellion in India to overthrow British rule. They published a newspaper also called "Ghadar," which was distributed widely among the Indian diaspora and smuggled into India to inspire nationalist sentiments and revolutionary activities. Lala Har Dayal was crucial in articulating the philosophy of the movement and mobilising support. The Komagata Maru incident in 1914 further fuelled the fire of the Ghadar movement, leading to attempts by Ghadarites to return to India and incite rebellion during World War I. Although the Ghadar movement did not achieve its goal of a nationwide revolt, it played a significant role in the history of the Indian freedom struggle, particularly in organising Indians abroad and inspiring future revolutionaries.
