I have to correct my self, the war length was not between 1-10 years, it was between 1-12 when I checked again.

And about "Hundreds of years of wars." I counted for fun how many years in total Sweden and Danmark was in war with each other between 1207 when the first war started to 1814 when the last one ended, and it was around 54 years in total, over a period of 4 centuries. (54 years are dependent how you count, if a war started 1207 and ended 1208 it could have been both 1 and 2 years long, so I counted 1,5 for all wars. So at best it was 47 years or at worst 64 with a mean time of 3,6 year per war).
