The Feast of the Queenship of Mary is celebrated every August 22. Our Lady is rightfully the Queen of the Universe, since she is the "Queen Mother" of Jesus Christ, the Lord and King of the Universe.
Blessed Anne Catherine Emmerich was given a beautiful vision of the Crowning of Our Lady as Queen of Heaven and Earth. These visions are contained in the book entitled "The Life of the Blessed Virgin Mary". Her vision of the coronation, which we share below, starts at the deathbed of Our Lady, as she is surrounded by the Apostles:
"Afterwards I saw the Apostles and disciples once more standing round the Blessed Virgin's bed and praying. Mary's face was radiant with smiles as in her youth. Her eyes were raised towards heaven in holy joy. Then I saw a wonderfully moving vision.
"The ceiling of the Blessed Virgin's room disappeared, the lamp hung in the open air, and I saw through the sky into the heavenly Jerusalem. Two radiant clouds of light sank down, out of which appeared the faces of many angels. Between these clouds a path of light poured down upon Mary, and I saw a shining mountain leading up from her into the heavenly Jerusalem. She stretched out her arms towards it in infinite longing, and I saw her body, all wrapped up, rise so high above her couch that one could see right under it.
"I saw her soul leave her body like a little figure of infinitely pure light, soaring with outstretched arms up the shining mountain to heaven. The two angel-choirs in the clouds met beneath her soul and separated it from her holy body, which in the moment of separation sank back on the couch with arms crossed on the breast.  My gaze followed her soul and saw it enter the heavenly Jerusalem by that shining path and go up to the throne of the most Holy Trinity.
"I saw many souls coming forward to meet her in joy and reverence; amongst them I recognized many patriarchs, as well as Joachim, Anna, Joseph, Elizabeth, Zechariah, and John the Baptist. The Blessed Virgin soared through them all to the Throne of God and of her Son, whose wounds shone with a light transcending even the light irradiating His whole Presence. He received her with His Divine Love, and placed in her hands a scepter with a gesture towards the earth as though indicating the power which He gave her. Seeing her thus entered into the glory of heaven, I forgot the whole scene round her body on the earth.
"Some of the Apostles, Peter and John for example, must have seen this too, for their faces were raised to heaven, while the others knelt, most of them bowed down low to the earth. Everywhere was light and radiance, as at Christ's Ascension. To my great joy I saw that Mary's soul, as it entered heaven, was followed by a great number of souls released from purgatory; and again today, on the anniversary, I saw many poor souls entering heaven, amongst them some whom I knew. I was given the comforting assurance that every year, on the day of the Blessed Virgin's death, many souls of those who have venerated her receive this reward.
"When I once more looked down to earth, I saw the Blessed Virgin's body lying on the couch. It was shining; her face was radiant; her eyes were closed, and her arms, crossed on her breast. The Apostles, disciples, and women knelt round it praying. As I saw all this there was a beautiful ringing in the air and a movement throughout the whole of nature like the one I had perceived on Christmas night. The Blessed Virgin died after the ninth hour, at the same time as Our Lord."
