The term Mizoram is derived from two Mizo words-Mizo and ram. 'Mizo' is the name used to call the native inhabitants and 'Ram' means 'land'. There is a dispute on the term 'zo'. According to one view, 'zo' means 'highland' and Mizoram means 'land of the Mizos'. B. Lalthangliana says 'zo' may also mean 'cold region' and therefore, Mizo may also signify people of the cold region.

The origin of the Mizos, like those of many other tribes in the northeastern India, is shrouded in mystery. The people living in the Mizo Hills were generally referred to as the Cucis or Kukis by their neighbouring ethnic groups which was also a term adopted by the British writers. The claim that 'The Kukis are the earliest known residents of the Mizo hills area,' must be read in this light. The majority of the tribes classified as "Mizo" today most likely migrated to their present territories from the neighbouring countries in several waves, starting around 1500 CE. `

Before the British Raj, the various Mizo clans lived in autonomous villages. The tribal chiefs enjoyed an eminent position in the gerontocratic Mizo society. The various clans and subclans practised slash-and-burn, locally called jhum cultivation - a form of subsistence agriculture. The chiefs were the absolute rulers of their respective clans' territories (ram), although they remained under the nominal political jurisdictions of the Rajas of Manipur, Tripura and Burma.

Prior to 1895, the year that the British Raj gained political control over Mizoram, there were many reports of head-hunting in the Mizoram area via tribal raids led by the village chieftains. Head-hunting was a practice which often involved the ambushing of a rival tribe, the taking of slaves and the cutting off of the heads of the defenders. These heads would sometimes be displayed at the entrances to the tribal village of the victors.

Some of the earliest records of raids and intertribal conflicts are from the early 19th century. In the 1840s, Captain Blackwood of Britain marched into the Mizo Hills with his troops to punish a Palian tribal chief for raiding British interests in India. A few years later, Captain Lester was wounded in a battle with the Lusei tribe in the region that is now Mizoram. In 1849, a Lusei tribal raid killed 29 members of the Thadou tribe and added 42 captives to their clan. Colonel Lister retaliated in 1850, with the co-operation of the Thadou tribe, an event historically called the First British invasion, burning down a Lusei village of 800 tribal houses and freeing 400 Thadou captives. British historical records on the Mizo Hills state that similar inter-ethnic tribal raids continued for decades after the First British Invasion. Such raids would be for the purpose of seeking out loot, slaves or retaliation for earlier lost battles.

By the time India gained independence from the British Empire, the number of tribal chiefs had increased to over 200. The educated elites among the Mizos campaigned against the tribal chiefdoms under the banner of the Mizo Union. As a result of their campaign, the hereditary rights of the 259 chiefs were abolished under the Assam-Lushai District Act, 1954. Village courts were re-implemented in the Mizo region along with other parts of Assam. Few Christian missionaries came to Mizoram during the colonial period knowing that the rural hill population was busy fighting among different tribes. The missionaries propagated Christianity with the support of the British government. As a result, majority converted to Christianity and changed their faiths without any resistance. The Mizos were particularly dissatisfied with the government's inadequate response to the 1959–60 mautam famine. The Mizo National Famine Front, a body formed for famine relief in 1959, later developed into a new political organisation, the Mizo National Front (MNF) in 1961.

Mizoram is a land of rolling hills, valleys, rivers and lakes. As many as 21 major hill ranges or peaks of different heights run through the length and breadth of the state, with plains scattered here and there. The average height of the hills to the west of the state is about 1,000 metres (3,300 ft). These gradually rise up to 1,300 metres (4,300 ft) to the east. Some areas, however, have higher ranges which go up to a height of over 2,000 metres (6,600 ft). Phawngpui Tlang also known as the Blue Mountain, situated in the southeastern part of the state, is the highest peak in Mizoram at 2,210 metres About 76% of the state is covered by forests, 8% is fallows land, 3% is barren and considered uncultivable area, while cultivable and sown area constitutes the rest.[34] Slash-and-burn or jhum cultivation, though discouraged, remains in practice in Mizoram and affects its topography. A report by Ministry of Environment, Forest and Climate Change in 2021 states that Mizoram has the highest forest cover as a percentage of its geographical area of any Indian state, being 84.53% forest.

Palak lake is the biggest in Mizoram and covers 30 hectares The lake is situated in Saiha district of southern Mizoram. It is believed that the lake was created as a result of an earthquake or a flood. The local people believe that a submerged village remains intact deep under the waters. The Tam Dil lake is a natural lake situated 85 kilometres from Aizawl. Legend has it that a huge mustard plant once stood in this place. When the plant was cut down, jets of water sprayed from the plant and created a pool of water, thus the lake was named Ţam Dil which means of 'lake of mustard plant'. Today the lake is an important tourist attraction and a holiday resort. The most significant lake in Mizo history, Rih Dil, is ironically located in Burma, a few kilometres from the Indo-Burma border. It was believed that departed souls pass through this lake before making their way to Pialral or heaven. Mizoram is also called a "peninsula state" as it is surrounded by international borders on three sides

Mizoram has a mild climate, being relatively cool in summer 20 to 29 °C (68 to 84 °F) but progressively warmer, most probably due to climate change, with summer temperatures crossing 30 degrees Celsius and winter temperatures ranging from 7 to 22 °C (45 to 72 °F). The region is influenced by monsoons, raining heavily from May to September with little rain in the dry (cold) season. The climate pattern is moist tropical to moist sub-tropical, with average state rainfall 254 centimetres (100 in) per annum. In the capital Aizawl, rainfall is about 215 centimetres (85 in) and in Lunglei, another major centre, about 350 centimetres (140 in). The state is in a region where cyclones and landslides can cause weather-related emergencies.

Mizoram has the third highest total forest cover with 1,594,000 hectares (3,940,000 acres), and highest percentage area (90.68%) covered by forests, among the states of India, according to 2011 Forest Survey of India. Tropical semi-evergreen, tropical moist deciduous, subtropical broadleaved hill and subtropical pine forests are the most common vegetation types found in Mizoram. Bamboo is common in the state, typically intermixed with other forest vegetation; about 9,245 km2 (44%) of the state's area is bamboo bearing. The state and central governments of India have cooperated to reserve and protect 67% of the land covered by forests, and additional 15% by management. Only 17% of the land is non-forested area for cultivation, industry, mining, housing and other commercial human activity. Satellite data suggests 91% of state's geographical area is covered by forests.

Mizoram has a population of 1,091,014 with 552,339 males and 538,675 females. This reflects a 22.8% growth since 2001 census; still, Mizoram is second least populated state of India. The sex ratio of the state is 976 females per thousand males, higher than the national ratio 940. The density of population is 52 persons per square kilometre.

The literacy rate of Mizoram in 2011 was 91.33 per cent, higher than the national average 74.04 per cent, and second best among all the states of India. About 52% of Mizoram population lives in urban areas, much higher than India's average. Over one third of the population of Mizoram lives in Aizawl district, which hosts the capital.

The great majority of Mizoram's population consists of several ethnic tribes who are either culturally or linguistically linked. These ethnic groups are collectively known as Mizos .Mizo people are spread throughout the northeastern states of India, Burma, and Bangladesh. They belong to numerous tribes; however, to name a particular tribe as the largest is difficult as no concrete census has ever been undertaken.

Sometime in the 16th century CE, the first batch of Mizo crossed Tiau River and settled in Mizoram and they were called as Kukis by Bengalis. The term Kuki mean the inhabitants of the interior and inaccessible mountain tracts. Sometimes grouped as Kuki-Chin tribes, The First batch were called Old Kukis, which are the Biate, Ranglong and the Hrangkhol, and the second batch that followed include Lushei Paite, Lai, Mara, Ralte, Hmar, Thadou, Shendus, and several other.

Mizoram has a highly literate work force, with literacy rate of nearly 90% and widespread use of English. The state has a total of 4,300 kilometres of roads of which 927 kilometres are high quality national highways and 700 kilometres of state highways. The state is developing its Kolodyne River for navigation and international trade. Mizoram's airport is at the capital city of Aizawl. The state is a power deficit state, with plans to develop its hydroelectric potential. After agriculture, the major employer of its people include handloom and horticulture industries. Tourism is a growth industry. In 2008, the state had nearly 7,000 registered companies. The state government has been implementing Special Economic Zones to encourage economic growth.
