The history of this Feast Day is attributed to St. Margaret Mary..    The Feast Day of the Immaculate Heart of Mary is always the day following the Feast Day of the Sacred Heart of Jesus.

17the Century:  St. Margaret Mary Alacoque was instrumental in beginning devotion to the Sacred Heart of Jesus after having visions.  This devotion involves receiving communion on the first Friday of each month for mine consecutive months to honor the Sacred Heart.  Jesus revealed His heart to her and emphasized the need for people to return His love through prayer and devotion.

In 1899 Pope Leo XIII consecrated the world to the Sacred Heart of Jesus.

The image of the Sacred Heart of Jesus is often shown with a crown of thorns and a flame.  This symbolizes Jesus’s infinite love, compassion and suffering for humanity.

The following prayer is from St. Leo XIII when he consecrated the world to the Sacred Heart.

Issued with the Encyclical Letter Annum Sacrum, 25 May 1899

Most sweet Jesus, redeemer of the human race, look down upon us, humbly prostrate before your altar. We are yours and yours we wish to be; but to be more surely united with you, behold each one of us freely consecrates himself today to your most sacred heart. Many, indeed, have never known you, many too, despising your precepts, have rejected you. Have mercy on them all, most merciful Jesus, and draw them to your sacred heart. Be you king, O Lord, not only of the faithful who have never forsaken you, but also of the prodigal children who have abandoned you; grant that they may quickly return to their father’s house, lest they die of wretchedness and hunger. Be you king of those who are deceived by erroneous opinions, or whom discord keeps aloof, and call them back to the harbor of truth and unity of faith, so that soon there may be but one flock and one shepherd. Be you king also of all those who sit in the ancient superstition of the Gentiles and refuse not you to deliver them out of darkness into the light and kingdom of God. Grant, O Lord, to your Church, assurance of freedom and immunity from harm; give peace and order to all nations, and make the earth resound from pole to pole with one cry: Praise to the divine heart that wrought our salvation; to it be glory and honor forever.
Amen
