WW2: The True Cost of War
Saturday, Channel 5, 8pm
The statistics behind the second World War are so staggering, it can be hard to get your head around them. Here's a few for starters: it cost more than a trillion dollars, 690 million people served in it, and between 50 and 70 million soldiers and more than 30 million civilians died in it. This new series suggests that the numbers can be used to help us understand the war's causes and some of the key strategic decisions made by the Nazis and the Allies. The first episode begins with the story of Franz Honiok, the 43-year-old farmer who is generally considered the first victim of the war. It also explores how no one was ready for the global conflict that would ensue when Germany invaded Poland.

Creedon's Atlas of Ireland
Sunday, RTÉ One, 6.30pm
What's your favourite Irish placename? Is it Termonfeckin or Hackballscross, or maybe Cloontyprocklis or Muckanaghederdauhaulia? John Creedon has always been fascinated by Irish placenames and their origins, so for his new series he sets off around Ireland to learn the meanings behind the placenames we all take for granted: "Placenames have been a source of fascination for me since childhood. I mean, NewTwoPotHouse is only out the road . . . how could you pass that without wondering about the story behind it?" Creedon's curiosity about Irish placenames led him to studying folklore in UCC, but in this three-part series he goes out in the field to visit the towns and villages, and uncover their hidden histories through the people who grew up in them. The first episode takes him to Derry, where he hangs out with members of The Undertones, and to Cavan, where his local guide is writer and Irish Time columnist Michael Harding.

BBC Proms: Mozart's Requiem
Sunday, BBC4, 7pm
Love and loss, life and death collide in an emotionally charged concert as Nathalie Stutzmann conducts the BBC National Orchestra and Chorus of Wales at the Royal Albert Hall. Turbulent shifts of mood characterise Brahms's Tragic Overture, and their ripples continue through the Prelude and Liebestod from Wagner's powerful operatic exploration of forbidden love, Tristan and Isolde. At the heart of the programme is Mozart's Requiem, the composer's final work, left unfinished at his early death, and his own musical epitaph. Soloists include Fatma Said and Kathryn Rudge.

The Queen's Lost Family
Sunday, Channel 4, 8pm

Getting impatient waiting for the new season of Netflix’s The Crown? You can get your fix of royal history from this new documentary series. Using personal letters, diaries and photograph albums, it charts the story of the royal family during the turbulent period between the 1920s and the end of the second World War. The first episode begins shortly after the first World War, when society is changing fast; monarchies have been toppled throughout Europe and most working men and many women have the vote. To keep pace with this new democratic age, George V uses his children to woo the public. But while Mary and Bertie are towing the line, brothers Edward, Henry and George are enjoying the roaring 1920s.
