Well unfortunately MA, your use of the term "illegal" in this case is misused in defining your argument.
When Columbus and his sailors landed on the islands of San Salvador in the Bahamas on October 12, 1492, they encountered peaceful, indigenous people
who brought them gifts, and thought that they were Gods. The ships and items the visitors brought were very impressive and foreign to them. The
natives were unarmed, yet bore scars from fighting off others who tried to take them as slaves. Nowhere that I have seen is it written that these
people had "laws" as we know them, against such visitations. Their friendly nature would serve as testament to that fact.
From the October 12, 1492, entry in his journal he wrote of them, "Many of the men I have seen have scars on their bodies, and when I made signs
to them to find out how this happened, they indicated that people from other nearby islands come to San Salvador to capture them; they defend
themselves the best they can. I believe that people from the mainland come here to take them as slaves. They ought to make good and skilled servants,
for they repeat very quickly whatever we say to them. I think they can very easily be made Christians, for they seem to have no religion. If it
pleases our Lord, I will take six of them to Your Highnesses when I depart, in order that they may learn our language."[18] Lacking modern weaponry
and even metal-forged swords or pikes, he remarked upon their tactical vulnerability, writing, "I could conquer the whole of them with 50 men, and
govern them as I pleased." [19]

Other sources write that Columbus and his men were extremely abusive, and even that they would routinely cut off pieces of these natives just to test
the edges of their knives and swords.
Their obsession with finding gold was evident when they had the natives sworn to find and bring them gold every three months, for which they would get
a copper pendant to be worn around their necks. Those without one would get their hands cut off and be left to bleed to death. With this kind of
treatment, it is no wonder the natives turned on them, but failed, as they were no match for the war hardened band of merciless sailors and their
swords and shields.
There was no negotiation. The natives were made to swear allegiance to the King and Christianity, or were killed. Most were taken as slaves or died
because of diseases brought by the sailors.
So it really wasn't a case of "illegal." It was case of imperialistic barbarism and the total subjugation and murdering of otherwise friendly
people who sought to help the visitors and admired them. Immoral? Oh yeah. Sad really.
But in the modern world all that has changed. Heh, or has it? The same things exists now to a degree, except with modern warships and weapons. The
term illegal though now does have application since the introduction of "law" onto the continent. And since those are the rules played by, the term
"illegal immigrant" has modern relevance.
