PARIS — A century ago this month, the great powers of an earlier order began to unravel. World War I redrew the world map, ending the Hapsburg Empire and the Ottoman Empire and shifting the tectonic plates beneath Europe and the Middle East in ways that still resonate. From June 28, the date in 1914 when a young radical assassinated Archduke Franz Ferdinand of Austria in Sarajevo, setting off a chain of events that started the war, to Nov. 11, the date that the Allies and Germany signed a first armistice ending the war in 1918, hundreds of cultural events are planned across Europe and the United States to observe the war’s 100th anniversary. Here are a few of them.

BELGIUM The country in whose Flanders Fields tens of thousands of soldiers died, is organizing a series of events for visitors to explore the battlefields, including a commemoration in Brussels on Nov. 11.

BOSNIA AND HERZEGOVINA On June 28 in Sarajevo, the Vienna Philharmonic will perform a memorial concert conducted by Franz Welser-Möst, with the choir of the National Theater of Sarajevo and featuring works bound to swell emotions. The program includes Haydn’s “Kaiserquartett,” written for the Austrian emperor, Schubert’s Symphony No. 7 (known as his “Unfinished Symphony”), Brahms’s “Schicksalslied” (“Song of Destiny”), and Three Pieces for Orchestra, Op. 6, by Alban Berg, written on the eve of the war. On June 27, the city will also screen “The Bridges of Sarajevo,” 13 short films about the city and its past by European directors including Jean-Luc Godard.

BRITAIN Far from triumphalism, the ghost of Virginia Woolf’s “Mrs. Dalloway,” with its war-ravaged protagonist, seems to loom over Britain’s World War I commemorations. It has organized some of the most inventive sounding events, from performance art to tours of stately homes that were converted for use in the war effort.
