Successful new world colonies were started by all except:

Columbus never sailed with Portuguese, but he did (he was actually Portuguese). 

It is little unknown, but Columbus (Cristobal Colón) sailed on some Portuguese expeditions on the African coast, although he was not the captain. At the time he was married to the Portuguese King cousin, daughter of the governor of the Madeira's Island. 

Later, he stole a (purposely fake) map from the King and went to Spain to sell his services. And the rest you already know...

                         Hope this helps :)

most are appointed by the president and confirmed by a vote in the senate. however, appeals court judges appoint federal bankruptcy judges, and district judges appoint federal magistrate judges. the qualifications for these positions vary depending on the preferences of the person reviewing nominees.

hope this , give me brainliest answer = )
