Question: How did the claims on the continent where the river that turns into the Tekezé is found, benefit the European powers?

<P0-S0> the cuyuni river is a south american river and a tributary of the essequibo river. <P0-S1> it rises in the guiana highlands of venezuela where it descends northward to el dorado, and turns eastward to meander through the tropical rain forests of guyana. <P0-S2> it finally turns southeastward, flowing to its confluence with the mazaruni river. <P0-S3> the cuyuni river marks the limit of the disputed territory of guayana esequiba for approximately . <SEP> <P1-S0> the subsequent great peace of montreal was signed in 1701 in montreal by 39 indian chiefs and the french. <P1-S1> in the treaty, the iroquois agreed to stop marauding and to allow refugees from the great lakes to return east. <P1-S2> the shawnee eventually regained control of the ohio country and the lower allegheny river. <P1-S3> the miami tribe returned to take control of modern indiana and north - west ohio. <P1-S4> the pottawatomie went to michigan, and the illinois tribe to illinois. <P1-S5> with the dutch long removed from north america, the english had become just as powerful as the french. <P1-S6> the iroquois came to see that they held the balance of power between the two european powers and they used that position to their benefit for the decades to come. <P1-S7> their society began to quickly change as the tribes began to focus on building up a strong nation, improving their farming technology, and educating their population. <P1-S8> the peace was lasting and it would not be until the 1720s that their territory would again be threatened by the europeans. <SEP> <P2-S0> The Atbarah River (; transliterated: Nahr 'Atbarah) in northeast Africa rises in northwest Ethiopia, approximately 50 km north of Lake Tana and 30 km west of Gondar. <P2-S1> It flows about 805 km (500 mi) to the Nile in north-central Sudan, joining it at the city of Atbarah (). <P2-S2> The river's tributary, the Tekezé (Setit) River, is perhaps the true upper course of the Atbarah, as the Tekezé follows the longer course prior to the confluence of the two rivers (at 14° 10' N, 36° E) in northeastern Sudan. <P2-S3> The Atbarah is the last tributary of the Nile before it reaches the Mediterranean. <SEP> <P3-S0> The major European powers laid claim to the areas of Africa where they could exhibit a sphere of influence over the area. <P3-S1> These claims did not have to have any substantial land holdings or treaties to be legitimate. <P3-S2> The European power that demonstrated its control over a territory accepted the mandate to rule that region as a national colony. <P3-S3> The European nation that held the claim developed and benefited from their colony’s commercial interests without having to fear rival European competition. <P3-S4> With the colonial claim came the underlying assumption that the European power that exerted control would use its mandate to offer protection and provide welfare for its colonial peoples, however, this principle remained more theory than practice. <P3-S5> There were many documented instances of material and moral conditions deteriorating for native Africans in the late nineteenth and early twentieth centuries under European colonial rule, to the point where the colonial experience for them has been described as "hell on earth." <SEP> <P4-S0> The Tekezé River rises in the central Ethiopian Highlands near Mount Qachen within Lasta, from where it flows west, north, then west again, forming the westernmost border of Ethiopia and Eritrea from the confluence of the Tomsa with the Tekezé at to the tripoint between the two countries and Sudan at . <P4-S1> After entering northeastern Sudan at the tripoint it joins the Atbarah River, which is a tributary of the Nile. <P4-S2> The Tekezé is perhaps the true upper course of the Atbarah, as the former follows the longer course prior to the confluence of the two rivers.
