Several different J1 SNPs and branches have completely different origins in the Westernmost area of Eurasia. Here, where the land ends and the sea begins only the strongest and most resolute individuals and groups could arrive at this extreme point of Europe after long and tough journeys. 

Northern Near Eastern types of J1 were associated with Indo-Iranian and Indo-European ancient basal J1 branches.  We can find in Western Iberia the Caspian-Iranic Old Christians J1 types like FGC6064 and M365 or Mediterranean and Semitic Jewish or Arab-Moorish types of J1 like P58.  

Portugal was the first viable post-Islamic society and the first fully developed post-Islamic Iberian State. Unlike the Basques, Catalans or Granadines, the Portuguese were the only ethnonational group in Iberia to keep their political independence, institutions, culture and their own language - defeating in several wars in Iberia and in South America - the authoritarian Castilian pressures away.  Portugal was a more powerful Christian reborn State, a Templar State, a Renaissance Crusader State, inventing the concepts of modern European National State and Ultramarine Seaborne Empire.  

Brazil is the mainstream branch of this movement (and Empire) and one of the biggest countries of the world nowadays. Brazilian Portuguese types of haplogroup J and J1 had to face Islamism and Judaism in the past.  

Both Semitic traditions contributed a lot in the history of the Portuguese Empire and both were defeated and expelled as religious additions, in the case of Judaism in Colonial Brazil they were expelled again during the Dutch Wars after they were defeated again in the New World. Individuals were free to convert to Christian-Catholicism and stay if they wanted. Islamism and Judaism only returned back in the modernity to Brazil as welcomed refugees and migrants in a more tolerant atmosphere where they were well integrated as long they respect the mainstream Brazilian traditions.
