[2] The colt entered the ownership of the Singaporean businessman Charles Ng and was sent into training with Ken Condon at the Osborne Lodge Stable, The Curragh, County Kildare.
He was from the eighth crop of foals sired by Holy Roman Emperor, one of the leading European two-year-olds of his generation, who unusually began his stud career as a three-year-old.
The colt made his debut on 7 May in the Listed Tetrarch Stakes at Naas Racecourse in which he encountered trouble in running before finishing sixth behind the Dermot Weld-trained Imaging.
"[8] In June Romanised was sent to England and started the 6/1 third choice for the St James's Palace Stakes at Royal Ascot but was never able to challenge the leaders and came home seventh of the ten runners behind Without Parole, beaten more than six lengths by the winner.
On his final start of the year Romanised was a 40/1 outsider when he finished ninth of eleven runners behind Roaring Lion in the Queen Elizabeth II Stakes at Ascot on 20 October.
The colt was then sent to England for the Group 1 Lockinge Stakes at Newbury Racecourse on 18 May and came home fourth of the fourteen runners behind Mustashry, Laurens and Accidental Agent.
In the Queen Anne Stakes at Royal Ascot on 18 June Romanised started a 25/1 outsider but belied his odds as he overcame repeated problems in attempting to obtain a clear run to finish a close fourth behind Lord Glitters, Beat The Bank and One Master.
On 20 July Romanised was dropped back in distance and class for the Group 2 Minstrel Stakes over seven furlongs at the Curragh and started the 2/1 second favourite behind the British-trained Hey Gaman (Prix du Palais-Royal).
All The King's Men led from the start before giving way to Hey Gaman but Romanised, who had raced in mid-division for most of the way, overtook the favourite inside the final furlong and won by a length to record his first victory in over a year.
The three-year-old filly Watch Me started favourite while the other fancied contenders included Study of Man, Shaman (runner-up in the Poule d'Essai des Poulains) and Line of Duty (Breeders' Cup Juvenile Turf).
Romanised settled in fifth place as his pacemaker Success Days disputed the early lead with Vocal Music before making a forward move 400 metres from the finish.
[13] Ken Condon stated that his trainee's owner Robert Ng was lodging an appeal commenting "He's a great sportsman but thinks it's a pretty cut and dried case.
After racing in third place he overcame some problems in running before overtaking the front-running favourite just inside the final furlong and drawing ahead in the closing stages to win by one and three quarter lengths.
"[17] In August Romanised attempted to repeat his 2019 success in the Prix Jacques le Marois but despite making some progress from the rear of the field in the last 400 metres he never looked to be a serious threat and came home fifth of the seven runners behind Palace Pier.
After a break of over two months the horse was dropped in class for a minor race on the Polytrack surface at Dundalk Stadium in November when he started odds on favourite but after taking the lead and looking the likely winner he was overtaken in the closing stages and finished third.
Condon commented "From when he first commenced fast work in the spring of his two-year-old year, Romanised showed that precocity, speed and class that were the hallmarks of his racing career.
