No, but there is the mention of a period of peace lasting about a generation before the arrival of Antichrist, and there's tons of private prophecy regarding the Great Monarch from some highly credible mystics.
While there certainly isn't anything about a Great Catholic Monarch in Scripture, are you talking about the period of peace in Apoc. 20?
And I saw seats; and they sat upon them; and judgment was given unto them; and the souls of them that were beheaded for the testimony of Jesus, and for the word of God, and who had not adored the beast nor his image, nor received his character on their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.  The rest of the dead lived not, till the thousand years were finished. This is the first resurrection.
Father Sylvester Berry disagrees that the Peace precedes Antichrist, as Scripture plainly places it after Antichrist:
Fr. Berry, The Apocalypse of St. John, Part III, Ch. XX, pp. 189, 190
But practically all interpreters who accept these conclusions take the reign of Antichrist as a prelude to the last judgment and the end of the world. Then, contrary to the plain sense of Holy Scripture, they place the universal reign of Christ before the time of Antichrist. This, in turn, makes the chaining of the dragon a difficult problem. p.189
After the defeat of Antichrist the Gentile nations will return to the Church and the Jєωs will enter her fold. Then shall be fulfilled the words of Christ: ''There shall be one fold and one shepherd.'" Unfortunately sin and evil will not have entirely disappeared, the good and the bad will still be mingled in the Church, although the good shall predominate. After many centuries, symbolized by a thousand years, faith will diminish and charity grow cold as a result of the long peace and security enjoyed by the Church. Then Satan, unchained for a short time, will seduce many nations (Gog and Magog) to make war on the Church and persecute the faithful. These apostate nations shall be promptly overwhelmed with a deluge of fire and the Church will come forth again triumphant. The general judgment and the end of the world will then be near at hand. p. 190
As does Fr. Kramer:
Fr. Kramer, The Book of Destiny, X. 1. xx., pp. 451, 452, 453.
Verse four is impossible of logical interpretation for those who place the thousand years chronologically ahead of the reign of Antichrist, because its contents are a positive contradiction of that theory.
The martyrs who shed their blood under Antichrist shall rule the world with Christ for a thousand years. They saved the world from utter destruction by their heroism; so they shall be specially honored by their own nation. They may receive control over the elements and whatever else influences human life, as many saints have had power of intercession against diseases, misfortunes and calamities.
During the thousand years also those shall rule with Christ who have faithfully held to the teachings of the Church, kept the commandments and practiced their religion in defiance of all danger, though they may have died from other causes. The language of verse 4 permits such interpretation. They have not submitted to Antichrist nor adored him nor received the imprint of his insignia on their foreheads or hands.
They will reign from Antichrist till the end of time. This places the THOUSAND YEARS after the advent and domination of Antichrist whom their courage and constancy defeats and overthrows.
Obviously, this creates problems for the private revelations which state that the GM precedes Antichrist, as Scripture plainly testifies to the reign of peace coming after the fall of Antichrist.
Which also, in my view, creates even more problems for the MHFM view of JPII as Antichrist (again, it's compelling
, but misses
a lot of marks, and I have yet to hear back from MHFM about some of these points they miss); as it is clear that Antichrist will proclaim that HE is the Messiah, the Christ, not just teach heresy about all men being Jesus Christ (like JPII, who has CLEARLY promulgated Antichrist's doctrine by dissolving Christ, 1 John 4:3). But at the same time, what compels me to their thesis is that spiritual destruction on a mass scale far, far outweighs any physical destruction. It's possible they are correct in stating that the First Beast, the Red Dragon, was Soviet Communism which has given way to the Second Beast and the Harlot which is the NWO and the Novus Ordo false religion, respectively, of which the Image of the Beast (Antichrist) sits atop the Harlot. So, if the NO is the prophesied Harlot, then the Antichrist has to have either come already or is to come soon as some sort of NO prelate or Antipope (given that the Papacy is the highest office in this world).
Interestingly enough, the 3.5 years commonly attributed to the reign of the Man of Sin is interpreted by Sig. Pastorini as a limit on the length of any given persecution in Church history:
Sig. Pastorini, History of the Christian Church, p. 61-62
In these various desolate abodes the Christians, though in appearance destitute of all human succour, were nevertheless fed and supported by a special divine providence for the space of a thousand two hundred and sixty days, or three years and a half, which was the utmost duration of any of the Roman persecutions; some of which did not fill that period, none exceeded it.
I don't see a period, in recent memory surrounding the Vatican II catastrophe, that fits such a period outside of the Council itself, which lasted 3 years and 2 months; or, possibly, the suppression of the Mass with the promulgation of the Novus Ordo Missae under Paul VI in 1969, albeit there's no definite period of time I've identified pertaining to it. Although Pastorini believes that no persecution will exceed it at any time.
As for worldly events, clearly the COVID lie we've been living through for 2.5 years now would fit such a period of persecution, as all who hold the name of Christian have suffered some form of persecution through its lockdowns and mandates.
