Wars can produce drastic changes in the attitudes and behaviour of the citizens of the countries involved in the fighting. Yet such conflicts also have important security and economic implications for uninvolved, ‘third-party‘ states. How do the wars of others shape domestic public attitudes? We explore this question by analysing the effect of the February 2022 Russian invasion of Ukraine on Spanish nationalism. Exploiting a natural experiment in Spain, we show that the Russian invasion caused a general increase in the salience of Spanish national identification, but not at the expense of regional or substate national identities. We also find an activation effect on electoral participation and increased support for taxation. Our study illuminates pathways through which international conflicts can impact domestic politics in third-party states.The project is organised around three thematic areas: (i) how trust within and between social groups and towards governance institutions emerges and evolves in contexts of rising inequality; (ii) how trust in unequal societies shapes governance outcomes through two intervening factors - political behaviour and social mobilisation; and (iii) the pathways through which changes in such intervening factors may sometimes result in inclusive governance outcomes, but in the breakdown of governance at other times. Each of these areas will incorporate detailed theoretical and empirical analyses at the subnational level in four countries - Colombia, Mozambique, Pakistan and Spain - affected by rising inequalities and characterised by unstable or strained democratic institutions. The absence of systematic qualitative, quantitative and behavioural data has hindered progress in understanding the links between inequality, trust and governance in countries outside North America and Western Europe. The project seeks to compile a number of unexplored data sources and collect new data comparatively across these other countries in order to fulfil this critical gap. This data collection will involve: (i) comparative individual-level surveys to understand contemporaneous levels of trust, and attitudes towards formal and non-formal local governing institutions, (ii) behavioural experiments under different inequality and political contexts to better understand the formation of trust under different scenarios, (iii) indepth interviews with key political actors in government, members of social movements and citizen organisations to understand how inequalities affect perceptions of governance and strategies of political mobilisation, and (iv) detailed compilation of archival data that will allow us to better understand how inequalities and attitudes have evolved across time and how different historical junctures may shape the governance outcomes we observe today.

Data were collected via an online survey designed by the dataset creators. It was scripted and hosted by the survey firm 40dB –following the dataset creators’ instructions. Potential participants were invited to take the survey because of their participation in an online panel with 40dB. The survey data includes data on 7,103 respondents, all Spanish citizens over 18 years old. The data was collected between 16 February 2022 and 10 April 2022.
