SOLIDUS is part of the research program “EURO-3-2014 European societies after the crisis” funded by Horizon 2020, a research and innovation programme of the European Union. Among Leipzig, there are partners from 13 different European Countries involved in the whole project.

Research Questions:
The current crisis has led to a loss of trust in European institutions. While the question of a rising European society is mainly discussed in the context of a European collective identity, little attention is paid to acts of solidarity and attitudes toward transnational solidarity within Europe. The SOLIDUS-Project, funded by the European Union, is trying to shed light on questions concerning European solidarity in several areas: spatial dimension of solidarity, inter- & outgroup-solidarity, activating social citizenship, gendering social policies and combating social exclusion. While broadening the knowledge and understanding of solidarity, the project also aims at working out strategies to foster and strengthen solidarity through policy-actors and public administration.

Overall, the SOLIDUS Project has the following objectives:

Get a better understanding of European solidarity in different fields of social life.
Examine psychological, political, cultural and socio-economic factors influencing solidarity.
Examine the expressions of solidarity and explore new approaches of identity transcending the nation-state conception of citizenship.
Contribute to policy-making to foster European solidarity.

Research Methods:
Beside several qualitative studies conducted by other project partners, Leipzig is responsible for conducting the ‘Transnational European Solidarity Survey’ – TESS to be carried out in 13 European countries. For each country, approximately 1000 completed interviews will be realized among respondents eligible to vote and aged 18 or older that will be chosen from national standard list assisted random digit dialing (RDD) and interviewed using CATI technique.
