Owing to his influential work in England (c 1543-1555) during the English Reformation, he is known to the English-speaking world by the Anglicised forms John a Lasco or John Laski. Both January Łaskis" coat-of-arms was Korab. Shortly after, he went to England, where in 1550 he was superintendent of the Strangers" Church of London and had some influence on ecclesiastical affairs in the reign of Edward VI. On the accession of Roman Catholic Queen Mary in July 1553, he fled to Copenhagen with a shipload of refugees from the Strangers" Church.
However they were denied refuge there because they would not accept the Augsburg Confession of Faith.
