 Through the five sessions of my course, you will be treated and empowered as citizens of Barcelona to reflect on several topics. The importance of urban communities and human solidarities, rules needed to channel the coexistence of very different people within a limited space. The balance between majorities and minorities required to build any republic, any political society. We will be using historical examples to illustrate problems and to discuss solutions. We will be working together on relevant cases, which happened in Barcelona eight, five, two centuries ago. Wow, some of these cases recently arose in the archives, where I often go in search of original documents. The cases will be dealing with very different issues. For instance, Barcelona local government, working men and women, religiosity, sex and adultery penalties. Through real stories, so we will be discovering Barcelona and its neighborhoods. We will be doing so in the classroom and also outdoors. After this course, you will be better skilled in social sciences, of course. And you will also understand why some markets or the opera house are built, where some conference used to be. Or why the Gothic Hospital near the Ramblas is still nowadays an amazing building.
