Yes doing the 1600th Sweden and French was very close and it become "fashon" to talk French and many of our word in our language is French word. And under 1150-1350 we was undersige from the "Hansa", an very rich and powerfull Merchant groupe from Hamburg, they had an ships called "knogg" and they pushed out the vikings, and they imposed a German sudo goverment and all "knecktar" (Hansa soldier) and they collected tax for "Hansa" and was very hated, and they was speaking only Germanic, and that was incoporated in to our language.
And from 1850 until today we are absorbing English..
