The last flag of the monarchy was used between 1830 and 1910. It is a blue-white beautiful flag that resurrects the initial and most used colors of the Portuguese state. By the time of the establishment of the Republic, the 1st Republic President wanted the flag to be maintained except the crown but another faction won the race to change the flag to green and red. Primary colors shouldn't be place together and a very vivid colored flag was established. A much criticized choice.
