how long does war last

The duration of wars can vary widely, ranging from a few years to several decades or even longer. Historically, wars have lasted anywhere from less than a year to nearly half a century or more. The average modern war lasts about 15 months, but large-scale or complex conflicts often extend for many years or even decades.

Historical Duration of Wars

  • Some historical wars, like the Hundred Years' War, lasted over 100 years intermittently.
  • Many wars have durations of 20 to 30 years, such as civil wars or long insurgencies.
  • Conflicts like the Cold War lasted about 45 years, although it was an indirect conflict.
  • Recent prolonged conflicts include ongoing wars lasting 20+ years, like the Afghanistan conflict and the Kurdish–Turkish conflict, which lasted over 40 years.

Factors Influencing War Duration

  • The scale and intensity of the conflict: Large-scale wars tend to last longer.
  • The nature of the conflict, such as conventional wars versus insurgencies or proxy wars.
  • Technological and logistical capabilities, which can either shorten or prolong warfare.
  • Political, economic, and social factors, including the willingness to negotiate or continue fighting.

Average Duration of Modern Wars

  • Statistical analysis shows an average duration of about 15 months for modern wars.
  • Some wars can become prolonged or even "eternal" if neither side achieves decisive victory or the conflict becomes frozen.

In summary, there is no fixed duration for how long a war lasts—it depends on many variables including the type of war, involved parties, resources, and geopolitical context. Wars can last from a few months to many decades or potentially indefinitely in some cases. Historical and modern examples demonstrate this wide range clearly.
