Several factors led to the beginning of World War I. The
most immediate cause was the assassination of the
Austrian archduke Franz Ferdinand by a Serbian nationalist
in 1914. As tensions exploded, many countries got
involved because their quest for power had led them to
form alliances that included mutual defense agreements.

gaining momentum as European nations raced to be the
first to colonize Asia and Africa. In many arenas,
nationalism was sweeping Europe, as each country fought
to defend its own dominance and power.
