Santa Catarina

Hi,gostaria de ajuda na tradução do seguinte texto:

The Azoreans settled on the coast. The inland regions were occupied in the XIX century by successive migratory waves of different European origins. Pioneering Germans, Italians, Poles, Ukrainians, Norwegians, among others, had to face the natural jungle-like surroundings, live from the land, and develop enterprising spirits. During the XX century, other Europeans, Asians and Arabs, as well as Brazilians from other regions, came to plant their dreams and hopes in Catarinense soil.

Além da translation,gostaria de saber como posso ler os séculos em numeros romanos, em ordinal ou cardinal??? Já ouvi falarem 20th(twentieth) century,is it right?
*Obs. As palavras in red são as que tenho mais dificuldade em traduzir. O que exatamente seria Jungle-like???
Thanks a lot
