It discouraged Alliances with supportive and sympathetic whites  

Explanation:

The Black power movement was all about achieving self determination for people of African American decent, it was all about blacks defending themselves against racial segregation, building their own political and Economic institutions and also having a self sufficient economy as well. and this clashed with the values of the civil rights movement which was about fighting for the civil right of everyone   .

The black power apparently supported racial segregation from people of other race and this discouraged Alliances with supportive and sympathetic whites because the black power movement constituted that the black race was superior    

the andes or andean mountains (spanish: cordillera de los andes) are the longest continental mountain range in the world, forming a continuous highland along the western edge of south america. this range is about 7,000 km (4,300 mi) long, about 200 to 700 km (120 to 430 mi) wide (widest between 18° south and 20° south latitude), and of an average height of about 4,000 m (13,000 ft). the andes extend from north to south through seven south american countries: venezuela, colombia, ecuador, peru, bolivia, chile and argentina.
