Ukraine has been going through a series of political and economic crises, notably the Euromaidan revolution and the Russian aggression and subsequent economic downturn. These events triggered fresh transnational diaspora-led activities such as the ‘London Euromaidan’ and the ‘Warsaw Euromaidan’. This paper analyses Ukrainian diaspora volunteerism in the UK and Poland and explores how the Ukrainian diaspora engages and contributes economically, socially, politically and culturally to the development of Ukraine. Drawing on fieldwork in both countries, three main findings were identified. First, due to the events in Ukraine, the Ukrainian diaspora has mobilised, grown stronger and became more united, whilst transforming from a more inward-looking to a more outward-looking community which, as a result, is now more and critically engaging with Ukrainian affairs. Second, the Ukrainian diaspora has the willingness, power and resources to contribute to the development of the home country, claiming to be recognised as an important stakeholder in the development of Ukraine. Thirdly, the Ukrainian government’s lack of recognition of the contribution of the Ukrainian diaspora is one of the most significant barriers to more comprehensive diaspora involvement in development.

This paper analyses diaspora advocacy on behalf of Ukraine as practiced by a particular diaspora group, Ukrainian Canadians, in a period of high volatility in Ukraine: from the EuroMaidan protests to the Russian invasion of Eastern Ukraine. This article seeks to add to the debate on how conflict in the homeland affects a diaspora’s mobilisation and advocacy patterns. I argue that the Maidan and the war played an important role not only in mobilising and uniting disparate diaspora communities in Canada but also in producing new advocacy strategies and increasing the diaspora’s political visibility. The paper begins by mapping out the diaspora players engaged in pro-Ukraine advocacy in Canada. It is followed by an analysis of the diaspora’s patterns of mobilisation and a discussion of actual advocacy outcomes. The second part of the paper inves-tigates successes in the diaspora’s post-Maidan communication strategies. Evidence indicates that the dias-pora’s advocacy from Canada not only brought much-needed assistance to Ukraine but also contributed to strengthening its own image as an influential player. Finally, the paper suggests that political events in the homeland can serve as a mobilising factor but produce effective advocacy only when a diaspora has already achieved a high level of organisational capacity and created well-established channels via which to lobby for homeland interests.
