Union Solidarity and Development Party
The Union Solidarity and Development Party is an ultranationalist, pro-military political party in Myanmar. Alongside the National League for Democracy, it is one of Myanmar's two principal national parties.
USDP is the successor to the former ruling military junta's mass organisation, the Union Solidarity and Development Association, and serves as the electoral proxy of the Tatmadaw, which operates as a state within a state. Many of its political candidates and leadership are retired generals. It supports authoritarian military leadership. USDP was founded by Prime Minister Thein Sein to contest the 2010 Myanmar general election; the party was headed by Sein until 2013. Since 2022, it has been led by Khin Yi, who was installed as a loyalist of military leader Min Aung Hlaing.
History
Establishment
The USDP was formed on 29 April 2010 by Thein Sein and senior military officers who had retired from the armed forces, in the lead-up to the 2010 Myanmar general election. On 6 July 2010, the military junta permitted its predecessor, the Union Solidarity and Development Association, to dissolve itself and transfer its assets and office to the USDP. This included assets from the USDA's conglomerate, the Myan Gon Myint group of companies, which had interests in key sectors of Myanmar's economy.2010 election
The USDP won the 2010 general election, which was boycotted by the opposition. On 2 May 2011, Shwe Mann assumed the office as temporary chairman of USDP. Htay Oo as deputy chairman, Aung Thaung and Thein Zaw as Secretary 1 and 2. Maung Oo was appointed as Disciplinary Official of the USDP. Former Yangon Mayor Aung Thein Lin was appointed to lead the USDP's Yangon branch.On 16 October 2012, Thein Sein was re-elected as the chairman of the Union Solidarity and Development Party at the USDP's first party conference in Naypyidaw. Because of mounting criticism over his dual role, Thein Sein handed over the position of USDP chairman to Shwe Mann on 1 May 2013. On 13 August 2015, it was reported that chairman Shwe Mann and general secretary Maung Maung Thein had been removed from their positions.
2015 election
In the lead-up to the 2015 general election, USDP member of parliament, Tin Aye stepped down to become chair of the Union Election Commission, the country's electoral regulatory body, prompting concerns over the UEC's lack of impartiality and independence.The opposition National League for Democracy contested the 2015 election. During the election, USDP secured less than 30% of the popular vote, gaining only 8.4% of elected seats in the Pyidaungsu Hluttaw.
2020 election and military coup
Following a second landslide victory for the National League for Democracy in the 2020 general election, the USDP baselessly alleged massive electoral fraud alongside the Tatmadaw, unsuccessfully challenged the election outcome in the courts, and called for the election to be re-run. After all constitutional means of challenging the election results were exhausted, the USDP supported the 2021 military coup d'état and assumed the presidency and multiple seats on the State Administration Council, the military junta.On 12 September 2022, Than Htay resigned as the party chairman and handed over immediately to Vice-Chairman Khin Yi, the latter became Acting Chairman. On 5 October 2022, Khin Yi was elected as the new Chairman and officially assumed the party chairmanship. In December 2022, the military junta began replacing hundreds of local government administrators in Yangon Region with USDP supporters.
The USDP was the first party to register under a new junta-enacted electoral law in 2023, and immediately began informally campaigning for the 2025–26 general election. The official campaign period began on 28 October 2025. Throughout the campaign, the USDP accounted for most campaigning, with other parties accounting for only a small share of events.
