Bhagat Singh, September 27, 1907 – March 23, 1931) was an Indian freedom fighter, considered to be one of the most influential revolutionaries of the Indian independence movement. He is often referred to as Shaheed Bhagat Singh (the word shaheed means "martyr").

Born to a family which had earlier been involved in revolutionary activities against the British Raj in India, Singh, as a teenager, had studied European revolutionary movements and was attracted to anarchism and communism. He became involved in numerous revolutionary organizations. He quickly rose through the ranks of the Hindustan Republican Association (HRA) and became one of its leaders, converting it to the Hindustan Socialist Republican Association (HSRA). Singh gained support when he underwent a 63-day fast in jail, demanding equal rights for Indian and British political prisoners. He was hanged for shooting a police officer in response to the killing of veteran freedom fighter Lala Lajpat Rai. His legacy prompted youth in India to begin fighting for Indian independence and also increased the rise of socialism in India

Bhagat Singh was born into a Jatt Sandhu family to Sardar Kishan Singh Sandhu and Vidyavati in the Khatkar Kalan village near Banga in the Lyallpur district of Punjab. Singh's given name of Bhagat means "devotee". He came from a patriotic Sikh family, some of whom had participated in movements supporting the independence of India and others who had served in Maharaja Ranjit Singh's army. His grandfather, Arjun Singh, was a follower of Swami Dayananda Saraswati's Hindu reformist movement, Arya Samaj, which would carry a heavy influence on Singh. His uncles, Ajit Singh and Swaran Singh, as well as his father were members of the Ghadar Party, led by Kartar Singh Sarabha Grewal and Har Dayal. Ajit Singh was forced to flee to Persia because of pending cases against him while Swaran Singh was hanged on December 19, 1927 for his involvement in the Kakori train robbery of 1925.

Unlike many Sikhs his age, Singh did not attend Khalsa High School in Lahore, because his grandfather did not approve of the school officials' loyalism to the British authorities. Instead, his father enrolled him in Dayanand Anglo Vedic High School, an Arya Samajist school. At age 13, Singh began to follow Mahatma Gandhi's Non-Cooperation Movement. At this point he had openly defied the British and had followed Gandhi's wishes by burning his government-school books and any British-imported clothing. Following Gandhi's withdrawal of the movement after the violent murders of policemen by villagers from Chauri Chaura, Uttar Pradesh, Singh, disgruntled with Gandhi's nonviolence action, joined the Young Revolutionary Movement and began advocating a violent movement against the British.

In 1923, Bhagat famously won an essay competition set by the Punjab Hindi Sahitya Sammelan. This grabbed the attention of members of the Punjab Hindi Sahitya Sammelan including its General Secretary Professor Bhim Sen Vidyalankar. At this age, he quoted famous Punjabi literature and discussed the Problems of the Punjab. He read a lot of poetry and literature which was written by Punjabi writers and his favourite poet was Allama Iqbal from Sialkot.

In his teenage years, Bhagat Singh started studying at the National College in Lahore,[12] but ran away from home to escape early marriage, and became a member of the organization Naujawan Bharat Sabha ("Youth Society of India").[2] In the Naujawan Bharat Sabha, Singh and his fellow revolutionaries grew popular amongst the youth. He also joined the Hindustan Republican Association at the request of Professor Vidyalankar, which was then headed by Ram Prasad Bismil and Ashfaqulla Khan.[citation needed] It is believed that he had knowledge of the Kakori train robbery. He wrote for and edited Urdu and Punjabi newspapers published from Amritsar. In September 1928, a meeting of various revolutionaries from across India was called at Delhi under the banner of the Kirti Kissan Party. Bhagat Singh was the secretary of the meet. His later revolutionary activities were carried out as a leader of this association. The capture and hanging of the main HRA Leaders also allowed him to be quickly promoted to higher ranks in the party, along with his fellow revolutionary Sukhdev Thapar.

Lala Lajpat Rai's death and the Saunders murder
The British government created a commission under Sir John Simon to report on the current political situation in India in 1928. The Indian political parties boycotted the commission because it did not include a single Indian as its member and it was met with protests all over the country. When the commission visited Lahore on October 30, 1928, Lala Lajpat Rai led the protest against Simon Commission in a silent non-violent march, but the police responded with violence. Lala Lajpat Rai was beaten with lathis at the chest. He later succumbed to his injuries. Bhagat Singh, who was an eyewitness to this event, vowed to take revenge.[citation needed] He joined with other revolutionaries, Shivaram Rajguru, Jai Gopal and Sukhdev Thapar, in a plot to kill the police chief. Jai Gopal was supposed to identify the chief and signal for Singh to shoot. However, in a case of mistaken identity, Gopal signalled Singh on the appearance of J. P. Saunders, a Deputy Superintendent of Police. Thus, Saunders, instead of Scott, was shot. Bhagat Singh quickly left Lahore to escape the police. To avoid recognition, he shaved his beard and cut his hair, a violation of the sacred tenets of Sikhism.

On April 8, 1929, Singh and Dutt threw a bomb onto the corridors of the assembly and shouted "Inquilab Zindabad!" ("Long Live the Revolution!").[15] This was followed by a shower of leaflets stating that it takes a loud voice to make the deaf hear.[16] The bomb neither killed nor injured anyone; Singh and Dutt claimed that this was deliberate on their part, a claim substantiated both by British forensics investigators who found that the bomb was not powerful enough to cause injury, and by the fact that the bomb was thrown away from people. Singh and Dutt gave themselves up for arrest after the bomb.[citation needed] He and Dutt were sentenced to 'Transportation for Life' for the bombing on June 12, 1929.

Last wish
Bhagat is said to have mentioned to Randhir Singh, prison inmate, Gadhar revolutionary and a known figure in Sikh circles, that he (Bhagat Singh) had shorn "hair and beard under pressing circumstances" and that "It was for the service of the country" that his companions "compelled him to give up the Sikh appearance" adding to it that he was "ashamed". He is seen with full unshorn hair in his later prison pictures and had expressed, as last wish before being hanged, the desire to get "amrit" from Panj Pyare including Randhir Singh and to adorn full 5 k's. However, his last wish, of getting "amrit" from Panj Pyare was not granted by the British

Death
Bhagat Singh was known for his appreciation of martyrdom. His mentor as a young boy was Kartar Singh Sarabha. Singh is himself considered a martyr for acting to avenge the death of Lala Lajpat Rai, also considered a martyr. In the leaflet he threw in the Central Assembly on 9th April 1929, he stated that It is easy to kill individuals but you cannot kill the ideas. Great empires crumbled while the ideas survived. After engaging in studies on the Russian Revolution, he wanted to die so that his death would inspire the youth of India to unite and fight the British Empire.

While in prison, Bhagat Singh and two others had written a letter to the Viceroy asking him to treat them as prisoners of war and hence to execute them by firing squad and not by hanging. Prannath Mehta, Bhagat Singh's friend, visited him in the jail on March 20, four days before his execution, with a draft letter for clemency, but he declined to sign it.
