Konstantin Trenchev

Konstantin Trenchev was born on 8 February 1955 in Stara Zagora. Family roots on both sides traced to Bansko. His father Dimitar Kostadinov Trenchev was a physician who led children's surgery at Stara Zagora's main hospital and was a Bulgarian Communist Party member; his mother was a nurse. A State Security summary later described the parents as fully approving their son's independent-union work. As a teenager he attended a French college in Algeria from 1968 to 1970, an unusual path for a provincial Bulgarian of that generation and one that left him with strong French and an outward-looking education.

Trenchev graduated in human medicine from the Higher Medical Institute in Sofia in 1982. In 1983 he became an assistant in anatomy, histology and embryology at the Higher Medical Institute in Stara Zagora. From 1987 he was an assistant in the department of general and clinical pathology there. He also worked in emergency medicine (Бърза помощ) and as an anatomopathologist. He was listed as an initiator and rationaliser of inventions recognised by Bulgaria's inventions institute (INRA). Later in life he spoke of returning to scientific work; with engineer Borislav Borisov he was credited as co-author of a water-plasma heating concept presented as an alternative to standard home heating.

Before 1989 Trenchev worked with other dissidents in the Independent Society for the Defence of Human Rights. In February 1989 he founded Confederation of Labour Podkrepa, the first independent trade union in Bulgaria under communist rule. Podkrepa's own memorial statement called the founding an act of civic courage and a defence of Bulgarian workers' dignity at a time when free association was impossible. For that activity he was repressed, arrested and held for several months as a political prisoner. A November 1989 State Security 'spravka' circulated among Grand National Assembly deputies described him as Kostadin Dimitrov Trenchev, noted Radio Free Europe interviews, visits to French, US and British embassies, encouragement of protests by Bulgarian Muslims, and charges under articles 273 and 321 of the Criminal Code. After release on bail he intensified organising. The repression cemented his public standing as a symbol of democratic and independent-union struggle.

After the regime fell, Trenchev was among the founders of the Union of Democratic Forces and a member of its National Coordinating Council in 1990 to 1991. He took part in the National Round Table talks between the ruling party and the opposition that framed Bulgaria's early transition. From May 2000 he was associated with the Democratic Alliance and from 9 July 2000 was its honorary chair. Throughout he remained first and foremost a union leader rather than a conventional party politician, and in later interviews he said he navigated politics with head rather than heart.

After 1989 Trenchev spent more than twenty-five years building Podkrepa into one of Bulgaria's two nationally representative union confederations. He was re-elected president in February 1997 and again persuaded to continue at the eighth congress in February 2011. The confederation developed strong sectoral and regional structures and a central role in social dialogue, conflict resolution, protests, national strikes and public campaigns. Thanks to his international work Podkrepa became the first Bulgarian union accepted into the European and international free trade-union family. Trenchev was the first Bulgarian elected vice-president of the European Trade Union Confederation and vice-president of the International Confederation of Free Trade Unions. In March 2006, writing for Podkrepa, he opposed IMF pressure to scrap length-of-service pay supplements and criticised what he saw as overly restrictive financial policy that raised the social cost of transition. In February 2015, after twenty-six years as president, he stepped down and was elected honorary president, the title he held until 2026.

A 1989 State Security file recorded that Trenchev had been divorced twice and was then married to Koyana Zheleva Ivanova-Trencheva (born 1 May 1964 in Stara Zagora), a medical student and active Podkrepa member who was then in France. An omda.bg biographical note updated in 2012 simply listed him as married. Detailed public information about later family life, children and private residence was limited. He remained closely identified with Stara Zagora and with Sofia through Podkrepa's national work. A funeral service was announced for 9 November 2026 at 12:00 in the Cathedral of Sveta Nedelya in Sofia.

Trenchev's public creed centred on freedom of association, workers' dignity, solidarity and refusal to treat those principles as negotiable. Podkrepa's memorial text stressed that he believed freedom and dignity must never be objects of compromise. In later media appearances he criticised the lack of a shared Bulgarian vision of the future, warned against abrupt coal-plant closures without replacement capacity, and denied personal enrichment from privatisation. He framed independent unionism as both a labour right and a democratic necessity forged under dictatorship.

In 2005 Trenchev received the Order of Stara Planina, first class, on the occasion of his fiftieth birthday and for public service. Internationally he was the first Bulgarian vice-president of the European Trade Union Confederation and of the International Confederation of Free Trade Unions. In 2015 Podkrepa elected him honorary president in recognition of his founding role and twenty-six years of leadership.

Trenchev's lasting mark is the existence of an independent Bulgarian trade-union tradition that began while communism still stood. Podkrepa remains one of the country's two nationally representative confederations and credits him with opening the door to European and international union membership. He is also remembered as a Round Table and early UDF figure who tied labour rights to the broader democratic transition. Dimitar Manolov and Podkrepa said generations of unionists would keep telling the story of his courage, consistency and refusal to compromise on workers' dignity.

After a short illness, Konstantin Trenchev died on 6 November 2026 at the age of 71. Podkrepa president Dimitar Manolov announced the death on Facebook; Bulgarian national media including BNT, Sofia Globe, 24 Chasa and Breaking.bg carried the confederation's tribute the same day. The specific medical cause was not made public beyond 'short illness'. A funeral service was set for 9 November 2026 at 12:00 in Sofia's Cathedral of Sveta Nedelya.
