From rent strikes to squatting, a new show reveals how people have managed to keep a roof over their head in London – and the mould and astronomical rents that persist

Charles Booth’s pioneering poverty maps of Victorian London show a vivid colour-coded warren of streets, alleyways and slums tightly packed together. Those marked black and dark blue were classed as being “very poor”, defined by “chronic want”. The light blue ones were poor – “18s to 21s a week for a moderate family”. Pink streets housed those who were “fairly comfortable”, and those where the wealthy lived were marked in yellow.

The maps by the British social reformer are the 19th-century equivalent of the modern-day indices of deprivation, which rank every geographic area of the UK by its level of social and economic disadvantage. Comparing the two shows how much has changed in the past 150 years – but also what hasn’t. Historical slums have been cleared away and housing conditions have generally improved, but extreme poverty and extreme wealth continue to live side by side in the capital.

A new play revisits the story of Ireland’s 18th-century German refugees, whose experience of prejudice and exclusion resonates with today’s debates over immigration

In the early 18th century, a few thousand Germans fled religious persecution and near starvation in their homeland and ended up in remote rural Irish villages. The Irish Palatines, as they were known, were poor, conservative homesteaders who couldn’t speak the language and were the object of suspicion and violence – precursors to the displaced Syrians or Afghans of the past decade.

Their story is told in Refuge, a co-production between Staatstheater Mainz and the Irish company Fishamble. Part love story, part social commentary, it is performed by a mixed cast, mainly in English but with some German interludes.
