Early histories of a war typically describe the war as it was declared by the states involved. It is not uncommon for later historians to group together a series of wars over a long period or spread over several theaters as part of a broader conflict or strategic campaign. The most familiar of these in the present day is probably the Cold War and the War on Terror, which included the Korean War (1950–1953) (Cold War), the Vietnam War (1965–1973) (Cold War), the Persian Gulf War (1990–1991) (Cold War), the War in Afghanistan (2001–2021) (War on Terror), and the Iraq War (2003–2011) (War on Terror) to name these five wars during the Cold War and the War on Terror. These groupings provide useful context for the wars involved. Note that some groupings overlap time periods and its possible for more than one war to be going on at the same time.
