After disintegration the empire Karolingov became an easy mark for enemies. The African and Spanish Moslems (moors) have attacked southern coast, have pushed aside inhabitants in internal areas of the country and have established the control over the western Mediterranean. From Asia through East and the Central Europe hordes of Hungarians which have broken through defensive works in the east have intruded and have got far on the West — to Burgundy and Provence. The most powerful and serious danger was represented, however, by attacks of Vikings in the end of 8 — the beginning 10 century from Scandinavia. These aggressors swimming along northern and west costs of France on the long open maneuverable courts, plundered settlements at coast, and then began to grasp and occupy the earths in the north of France. Such purpose was put, apparently, before itself by army of the Vikings besieging Paris in 885–886, and only thanks to heroic defenders over which count Odo and bishop Gozlen Parisian supervised, Vikings managed to be rejected from city walls. Charles Lysyj could not assist and has lost a throne. The new king in 887 became count Odo Parisian. Local feudal leaders for protection of the possession against Vikings increased a set of recruits and erected fortresses in strategically important places. However in one area — between the river Somme and Brittany — the leader of Vikings of Rollonu managed to be fixed, and king Charles Prostoj from dynasty Karolingov was compelled to recognise its rights to these earths under condition of a recognition of the Supreme royalty. In this area which became known as duchy Normandy, Vikings have quickly acquired ôðàíêñêóþ culture and language and have been assimilated by local population. The vague period between 887 and 987 in a political history of France is noted by struggle between Karolingov came from count Odo and a dynasty. This struggle exhausted France up to 987 when large feudal magnates have preferred a sort of Odo and have selected king Gugo Kapeta, the column Parisian.
