That second Miguel never visited Portugal in his life.Only a few hundereds of people still fight to make believe there ever was a Miguel II. But they have been quite active in this forum 
You should take care of what you say or you will make a fool of yourself.
The Liberator D.Pedro, who had already usurpated the brazilian throne from his father and became a foreign citizen, after being banned from the country he usurpated, decides the tropical air is not good for his health and chooses to come home, the land of his forefathers.
Unfortunately the throne of Portugal is occupied by his brother D.Miguel, so why not start a ravaging civil war and ruin even more the country after the pilliage the french and the english have done ?
D.Pedro wins the civil war and his brother, the rightful king D.Miguel, is sent to exile.
Just like that ? No ! D.Pedro offers D.Miguel a law stating that anybody is entitled to kill him or any of his descendants yet to be born, should he ever enters Portugal again.
Not the police or the army, but any citizen like you or me.
In spite of that, some authors refer that even so, there was a private and secret meeting at Mafra Palace between D.Miguel and D.Pedro V.
Does that make D.Pedro V a traitor for not shooting his uncle :-o ?
As to D.Miguel II, he also visited Portugal more than once.
There is that very wellknown episode when he arrived in Lisbon with his sister Infanta D.Aldegundes and her husband Enrico de Borbon-Parma, duke of Bardi, on the latter's yacht Adelgonda
The couple visited Lisbon, quite discretely, although the Home Office knew of their presence and alerted King D.Luis, who did nothing.
D.Miguel, his sister and his brother-in-law, decided to go to the São Carlos Theater, where they were recognized.
In a very subtle way, the Home Office advised them to leave the country.
So, jeopardising his life, D.Miguel II DID VISIT PORTUGAL.
Do your homework before spilling your poison ;-)
