The fighting in the Gallipoli Campaign of World War I had naval and air dimensions. Most of the fighting, however, took place on the land of the Gallipoli Peninsula itself between ground troops of both sides. This spit of land is located to the north of the Dardanelles Straits.
The war lasted 6 years
Jerusalem and The Holy Land
the fighting took place in three continents Africa Asia Europe and if you count north America that's 4 continents
The war covered the entire country but most of the fighting took place south of the DMZ.
There were two countries that saw most of the fighting, as the Western Front stretched across France and Belgium. I am not aware of which country got the worst of it. Probably France because they had the two Battles of the Somme.
