The district was established under British rule in 1818 and on establishment constituted the then tehsils of Meerut, Ghaziabad, Mawana, Baghpat, Sardhana and Hapur. These now constitute the districts of Meerut, Ghaziabad, Hapur, Bagpat, Muzaffarnagar, Bulandshahr and a part of Gautam Buddh Nagar district.
Meerut also contained a Harappan settlement known as Alamgirpur. It was also the easternmost settlement of the Indus valley civilisation. Meerut had been a centre of Buddhism in the period of Mauryan Emperor Ashoka (r. 273 BC to 232 BC.), and remains of Buddhist structures were found near the Jama Masjid in the present day city. The Ashoka Pillar, at Delhi ridge, next to the 'Bara Hindu Rao Hospital', near Delhi University, was carried to Delhi from Meerut, by Firuz Shah Tughluq (r. 1351–1388); it was later damaged in a 1713 explosion, and restored in 1867.
In the eleventh century AD, the south-west part of the district was ruled by Har Dat, the Dor Raja of Bulandshahr who built a fort, which was long known for its strength and finds mention in Ain-i-Akbari. He was later defeated by Mahmud Ghazni in 1018. A prominent local landmark, the Jama Masjid, dates from this period and is said to have been built by Mahmud's vizir. Shortly after its capture the city was regained by the local Hindu Raja and part of his fortifications, built for the city's defence, survived until recent times. The first big invasion on the city came later in 1192 AD, from Mohammad Ghori, when his general Qutb-ud-din Aybak attacked the city, and a much worse fate lay ahead for the district, which came with the invasion of Timur in 1398, during which the Rajputs offered a tough resistance at the fort of Loni, where he fought the Sultan of Delhi, Muhammad Tughlaq. But, eventually they were all defeated and all the 1,00,000 prisoners his army had taken in since his invasion of India were massacred, according to Timur's own accounts in Tuzk-e-Taimuri. Thereafter he went on to attack Delhi, where he again massacred the local population, and returned to attack Meerut town, then ruled by an Afghan chief, Ilias, and took the city in two days, leading to widespread devastation, before heading north once again.
The city then came under the rule of the Mughal Empire and saw a period of relative tranquility. During the rule of Mughal Emperor, Akbar the Great (r. 1556–1605), there was a mint for copper coins here. During the decline of the Mughal Empire, after the death of Aurangzeb, the city came effectively under the control of local chieftains, the Saiyids of Muzaffarnagar in the north, the Jats in the south-east, and the Gujars along the Ganges and in the south-west. The city saw Sikh and Maratha invasions in the 18th century, with interruptions by Jats and Rohillas. Walter Reinhardt, an English soldier, established himself at Sardhana and some parts of the district came under his rule. Upon his death, they came into the hands of Begum Samru. During this time, the southern part of the district had remained under Maratha rule. In 1803, with the fall of Delhi, Daulat Rao Scindia of the Marathas ceded the territory to the British. The city was made headquarters of the eponymous district in 1818.
Meerut is famously associated with the Indian Rebellion of 1857 against the British East India Company. The famous slogan "Dilli Chalo" ("Let's march to Delhi!") was first raised here. Meerut cantonment is the place where the rebellion started when Hindu and Muslim soldiers were given rifle cartridges rumoured to have a coating made of animal fat. The bullet wrapping was to be opened by mouth before use, which affected the religious sensibilities of both Muslims and Hindus as the fat used was alleged to be derived from lard and tallow; cows are held sacred by Hindus and Muslims consider the pig unclean. Meerut soldiers set fire to the bungalows of the English.
During this revolt, Meerut leapt into international prominence, when on 24 April 1857 eighty-five of the ninety troopers of the 3rd Cavalry refused to touch the cartridges and after court-martial were sentenced to ten years imprisonment. On Sunday, 10 May 1857, Kotwal Dhan Singh Gurjar opened the gates of the prison. These soldiers, along with other imprisoned soldiers escaped prison and declared themselves free, revolted, attacked and killed several of the British authorities to take the city in their control. This marked the beginning of a widespread revolt across northern India as these soldiers marched towards Delhi. 10 May is still celebrated as a local holiday in Meerut.
Meerut was also the venue of the controversial Meerut Conspiracy Case in March 1929, in which several trade unionists, including three Englishmen, were arrested for organising Indian-rail strike. This immediately caught attention back in England, inspired the 1932 play titled Meerut Prisoners, by Manchester street theatre group, the 'Red Megaphones', highlighting the detrimental effects of colonisation and industrialisation Electricity was brought to Meerut in 1931. In the 1940s, Meerut cinemas had a "Don't Move" policy during playing of the British national anthem. The last session of the Indian National Congress before Indian independence was held at Victoria Park in Meerut on 26 November 1946. It was in this session that the Constitution-making committee was constituted.
The city and district also suffered from communal (Hindu-Sikh) riots in 1984 and (Hindu-Muslim) riots in 1982 and in 1987, during which the Hashimpura massacre took place, in May 1987, when personnel of the Provincial Armed Constabulary (PAC) allegedly shot dead 42 Muslims, the trial of the case is still pending. In 2006, a fire at a consumer electronics "Brand India" fair in Victoria Park Stadium killed over 100 people. But, according to some unofficial sources, the number of affected people is pegged at more than 200.
