The Equestrian statue of Bartolomeo Colleoni is a Renaissance sculpture in Campo Santi Giovanni e Paolo, Venice, Italy, executed by Andrea del Verrocchio in 1480-1488.
 Portraying the condottiero Bartolomeo Colleoni (who served for a long time under the Republic of Venice), it has a height of 395 cm excluding the pedestal.
 It is the second major equestrian monument of Italian Renaissance, after Donatello's Equestrian statue of Gattamelata (1453).
The Monument to Nicholas I (Russian: Памятник Николаю I ) is a bronze equestrian monument of Nicholas I of Russia on St Isaac's Square (in front of Saint Isaac's Cathedral) in Saint Petersburg, Russia.
 Unveiled on July 7th [O.S. June 25th] 1859 , the six-meter statue was a technical wonder of its time.
 It was the first equestrian statue in Europe with only two support points (the rear hooves of the horse), the only precedent being the 1852 equestrian statue of U.S President Andrew Jackson.
The Virginia Monument is a Battle of Gettysburg memorial to the commonwealth's "Sons at Gettysburg" (Battlefield) with a bronze statue of Robert E. Lee on his horse Traveller and a ""bronze group of figures representing the Artillery, Infantry, and Cavalry of the Confederate Army"".
 The equestrian statue is atop a granite pedestal and the group of six standing figures is on a sculptured bronze base with the figures facing the Field of Pickett's Charge and the equestrian statue of Union General George G. Meade on Cemetery Ridge.
An equestrian statue is a statue of a rider mounted on a horse, from the Latin ""eques"", meaning "knight", deriving from ""equus"", meaning "horse".
 A statue of a riderless horse is strictly an "equine statue".
 A full-sized equestrian statue is a difficult and expensive object for any culture to produce, and figures have typically been portraits of rulers or, more recently, military commanders.
Indirect presidential elections were held in Finland in 1943.
 The 1937 electoral college was recalled and re-elected Risto Ryti, who received 269 of the 300 votes.
 President Ryti was ready to remain in office and to try to lead Finland successfully through World War II.
 Nevertheless, some Finnish politicians believed that Marshal Mannerheim, the Commander-in-Chief of the Finnish army, would lead Finland more effectively.
 In a test vote, 147 presidential electors out of 300 supported Mannerheim.
 This plurality was not, however, enough for Mannerheim who required an assured majority of electors to back him for his presidential candidacy.
 Having failed to receive this majority's support, Mannerheim withdrew his candidacy and Ryti was overwhelmingly re-elected President.
Aimo Johan Kustaa Tukiainen (1917–1996) was a sculptor from Finland.
 His best-known work is the Equestrian statue of Marshal Mannerheim in Helsinki.
Major General John A. Logan, also known as the General John A. Logan Monument and Logan Circle Monument, is an equestrian statue in Washington, D.C. that honors politician and Civil War general John A. Logan.
 The monument is sited in the center of Logan Circle, a traffic circle and public park in the Logan Circle neighborhood.
 The statue was sculpted by artist Franklin Simmons, whose other prominent works include the Peace Monument and statues in the National Statuary Hall Collection.
 The architect of the statue base was Richard Morris Hunt, designer of prominent buildings including the Metropolitan Museum of Art in New York City and The Breakers in Newport, Rhode Island.
 Prominent attendees at the dedication ceremony in 1901 included President William McKinley, members of his cabinet, Senator Chauncey Depew, Senator Shelby Moore Cullom, and General Grenville M. Dodge.
Baron Carl Gustaf Emil Mannerheim (] ; 4 June 1867 – 27 January 1951) was a Finnish military leader and statesman.
 Mannerheim served as the military leader of the Whites in the Finnish Civil War, Regent of Finland (1918–1919), commander-in-chief of Finland's defence forces during World War II, Marshal of Finland, and the sixth president of Finland (1944–1946).
Monument of Aemilius Paullus was erected in the Sanctuary of Apollo at Delphi.
 Dating back to 167 BCE, the monument commemorates the Roman victory in the Battle of Pydna against King Perseus of Macedon.
 The partially completed pillar was intended to be a base for a portrait of King Perseus.
 It was originally created to make the Macedonian presence known in Delphi to remind the Delphians of the tradition of friendship existing between them and the royal family.
 However, the monument was taken over by Aemilius Paullus to celebrate himself and Rome's victory noting that, "it was only proper that the conquered should give way to the victors."
 The Monument of Aemilius Paullus stood in front of the Temple of Apollo along with two other commemorative pillars to Eumenes II of Pergamon and Prusias II of Bithynia.
 However, this pillar dominates over the other two.
 The completed monument was a bronze equestrian statue atop a rectangular pillar that soared over 9 meters high.
 While the equestrian statue that was originally on top of pillar no longer remains, the cuttings in the plinth show that the horse would have been in a rearing position.
 An inscription near the base of the altar survived, which translated reads, "Aemelius, son of Lucius set this up from the spoils which he took from King Perseus and the Macedonians."
