Thaba Bosiu is a sandstone plateau with an area of approximately 2 km2 and a height of 1,804 meters above sea level. It is located between the Orange and Caledon Rivers in the Maseru District of Lesotho, 24 km east of the country's capital Maseru. It was once the capital of Lesotho, having been King Moshoeshoe's stronghold.

Thaba Bosiu was used as a hideout by Moshoeshoe I and his subjects after they migrated from Butha-Buthe in 1824 escaping the ravages of the Difaqane/Mfecane Wars. The plateau formed a natural fortress which protected the Basotho in times of war. Moshoeshoe I and his people took occupation of this mountain in July 1824. He named it Thaba Bosiu (loosely translated – Mountain at Night) because he and his people arrived at night. To intimidate his enemies, he spread news that the mountain grew larger than usual at night. Moshoeshoe I was able to offer cattle and protection to those fleeing the ravages of Mfecane/Difaqane Wars. When Moshoeshoe settled in Thaba Bosiu, he sent for many people to be wound up by his regiments. They were given food and shelter. The plateau's large area meant it could hold enough livestock and provisions to support the people during a lengthy siege.
Once satisfied that they were safe, he sent them out, but a lot remained under his rule. This gave birth to the Basotho nation. Thaba Bosiu served as a capital for his new Basotho nation. It also became the centre of organised resistance to European encroachment into the central plateau region of South Africa.
The mountain has eight springs and six passes, the main one being Khubelu pass. The other passes are known as Ramaseli, Maebeng, Mokachane, Makara and Rahebe. It is flat topped and is situated in the valley of the Phuthiatsana River. It is approximately 24 km east of the junction of the Caledon River that divides Lesotho from Free State. It rises about 106m from the surrounding valley and its summit is surrounded by a belt of perpendicular cliffs some 12m on the average. Nearby, there are San paintings.
In 1837, Private David Webber from the 72nd Seaforth Highlanders reached Thaba Bosiu, where he was given refuge/sanctuary. He was a good mason and carpenter, and thus built Moshoeshoe I a stone house. It was a rectangular building measuring 10 metres by five metres and was divided internally into two rooms. Moshoeshoe I had four other stone buildings erected as part of his compound – three of which were rectangular and one cylindrical.
Many Basotho believe that the mountain preserved magical properties. One belief is that if an individual takes some dirt from the mountain, he will find that it is gone in the morning, having returned to the mountain. As also mentioned above, news was spread as a form of intimidation to the enemies that the mountain grew larger at night.
European invaders in 1852 and the Boers of the Orange Free State were unable to storm Moshoeshoe's mountain during the siege of Thaba Bosiu on 18 August 1865. Louw Wepener and 6 000 armed Boers volunteered to charge Thaba Bosiu. Their strategy was simply for the Free State Artillery (Vrystaatse Artillerie Regiment) to bombard the top of the mountain. As they approached, only 100 Boers were still with Wepener by 5pm and others had retreated to the Boer lines. Wepener made it to the top of Khubelu pass only to be struck by a bullet on his head. He is the only enemy ever to reach the mountain top and has been linked to it as Khubelu pass is also known as Wepener's pass. The siege of Thaba Bosiu continued until January 1866 when General Jan Fick and his men returned to Free State to reorganise.
Treaty of Thaba Bosiu
Due to being starved after the siege, the Basotho signed a treaty in April 1866, in which they agreed to surrender 3 000 cattle. They also surrendered more than two-thirds of their arable land. At the time, Basotho faced large scale starvation and thus Moshoeshoe and his subjects agreed to the Orange Free State terms. The land they forfeited during this treaty included conquered territory on the west of the bank of the Caledon River and Orange River. This left Basotho with an incredibly reduced cultivable area close to Thaba Bosiu, as well as 32km of arable soil on the east bank of the Caledon River. Villagers, however, did not vacate the surrendered territory and in March 1867, Orange Free State President Johannes Henricus Brand ordered both a resumption and intensification of Free State military action.
After the Third Free State Basotho War, in 1867 when Free State conquered the whole Lowlands, Moshoeshoe requested British protection which was granted in March 1868 when Lesotho on the eve of the Boer attack on Thaba Boisu, became a British territory. Thaba Bosiu was the only territory which remained invincible.
Thaba Bosiu Affair
On 27 December 1966, Moshoeshoe II organised protest meetings which culminated in a prayer meeting at Thaba Bosiu. This was a reaction to Prime Minister Chief Leabua Jonathan’s governance (leader of the Basotho National Party - BNP). Moshoeshoe II contested the legitimacy of the BNP governance and his lack of executive powers in the governance of Lesotho. When the prayer meeting was held, Chief Jonathan perceived this defiance as a promotion of insurrection and banned the meeting. A conflict between the security forces and demonstrators ensued, resulting in 10 dead and arrests of many opposition party leaders. Under house arrest, Moshoeshoe II was forced to sign a document promising not to convene or address public gatherings without consent of his government and to present only speeches required and prepared by the government. 
In 1967, the Lesotho government declared the mountain a national monument. In the 1990s, the United Nation Development Programme in conjunction with the Basotho government, initiated the Preservation and Presentation of Thaba Bosiu, the national monument to preserve this historical landmark. This mountain has become a tourist attraction, with a conference centre, a cultural village and many rondavel type of accommodation.
In 1996, Moshoeshoe II was buried on the mountain, joining Moshoeshoe I. To keep the cultural significance, several political organisations held meetings or rallies at Thaba Bosiu. For example, Lekhotla la Bafo (a political organisation) held many meetings on top of the mountain. In 1957, Lekhotla la Bafo held a joint meeting with the Basotoland Congress Party (BCP) at Thaba Bosiu.
