Mantua is situated in the Po-valley and was a buffer state between the powerful neighbors Milan, Venice, Ferrara, Parma and the Papal State. The dynasty of the Gonzaga emerged from the Gonzaga castle near Mantua. Ludovico I Gonzaga attained to power in Mantua in 1328 and was recognized as imperial vicar in 1329. As a result, the territory expanded. The Gonzaga were charged over the time to Counts (1382), Margraves (1433) and finally to Dukes of Mantua (1530). In 1536 they took over the Margravate Monferrato.

Gianfrancesco I Gonzaga, 1407-1444
- 1433 first Margrave of Mantua -
Gianfrancesco I (*1394) served various states as condottiere - the Papal States (1412), the Malatesta (1417) and Venice (since 1432), where he ascended to 'generale capitano' (commander-in-chief). His alliance with Venice led Mantua win territory in the west. However, later territories were lost in the east, while being in service of the Visconti of Milan. Emperor Sigismund made him hereditary Margrave of Mantua in 1433 for a payment of 12000 florins and a promise of marriage.
Gianfrancesco I promoted the reputation of his family through his work as a patron. He took the humanist Vittorino da Feltre to the court as an educator of his children. He attracted artists such as Pisanello to Mantua, promoted the education of poor children and founded the first manufactory for tapestries in Italy. Gianfrancesco I made so Mantua to a leading city of the Renaissance.

This medal was probably ordered by his son and successor.
Much later Archduke Ferdinand commissioned a small painting for his portrait collection at Ambras Castle, which apparently bases on the medal.

None of his coins already bear his portrait.
Coat of arms: One of the first coins issued just after his elevation in 1433 is a Grosso (ō 25 mm, 2.4 g.), which presents for the first time the newly created coat of arms of the margravete of Mantua.
The original coat of arms of the Gonzaga was divided in alternating three golden and three black bars. Emperor Wenceslas (1378-1419), king of Bohemia, donated in 1394 the increase with the Bohemian lion (standing, crowned and double-skinned). The background coat of arms (cross with four eagles) was donated on the occasion of the elevation to the margravate (1433).
The take over of Monteferrato (1536) brought further coats of arms, see below.

Ludovico II Gonzaga, 1444-1478
- 2nd Margrave of Mantua -   - named "Luigi il Turco" -   - modern counting: Ludovico III -
Ludovico II (*1423) married Barbara of Brandenburg, a niece of Emperor Sigismund, on the occasion of Mantua's elevation to a Margravate in 1433. Ludovico was condottiere like his father and served different powers. Some of them were mutual enemies. When Ludovico entered Milan's services, but his father was in Venice services, a conflict erupted. After the father changed to Milan (1438), they were reconciled again (1441).
Ludovico succeeded his father Gianfrancesco as 2nd Margrave of Mantua in 1444. Through inheritance of his brothers and the high costs of war, the county was in economically bad shape. Mantua won reassert, as Pope Pius II called for a council to Mantua (1459-1460), to launch a crusade against the Turks as a late response to the fall of Constantinople. At the end of the Council, the Pope rose Ludovico's second son Francesco to a cardinal.
Ludovico committed the humanist author and architect Leon Battista Alberti (1404-1472) to Mantua. He also appointed Andrea Mantegna to the court artist and let him create the famous 'Camera degli Sposi' frescoed drawings (1465-1474) in the ducal Castello. Ludovico II is immortalized there together with his family on two frescoes.

Federico I Gonzaga 1478-1484
- 3rd Margrave of Mantua -
Federico (*1441) served the Sforza in Milan as condottiero against Venice. 1478 he succeeded his father in Mantua, but had to cede land to his brothers. He married to Margaret of Bavaria. He was known for his affection for his children and kindness towards the court painter Mantegna, who more than any artist seemed to be a part of the family. The eldest son Francesco succeeded him, another son Sigismondo became Cardinal.

Francesco II Gonzaga, Margrave of Mantua 1484-1519
- 4th Margrave of Mantua -
Francesco (*1466) was a significant Condottiere, politician and patron in a time of great political unrest in Italy. As Condottiere he changed several times between Italian and French masters, but always was able to preserve the independence of Mantova.
Francesco married in 1490 Isabella d'Este from the house Este in Ferrara. Isabella was beautiful, intelligent and well educated. She represented her husband during his absence with diplomatic skills to the benefit of Mantua. When Francesco 1519 died of syphilis, Isabella served as regent for her son Federico II. In the time of Francesco and Isabella Mantua reached to a glittering highlight, in particular by Isabella's activities as patron. She was painted by artists such as Raphael, Andrea Mantegna, Titian and Leonardo da Vinci. Isabella knew best how to use art for the prestige for the house Gonzaga.

The revers presents a so-called 'impresa', that is a figure accompanied by a related motto.
The 'impresa' refers to the Battle of Fornovo (1495): Francesco wants
to depict his conduct as commander to be as pure as gold which melts in the crucible.
King Charles VIII had entered unhindered Italy to take Naples. Soon after his arrival there, a Holy League against him formed in Italy and he hurriedly retreated back. In the Battle of Fornovo (near Parma), the troops of the League, led by Francesco Gonzaga, wanted to defeat the French. Both sides declared themselves victors, although the outcome of the battle remained undecided, because Charles was able to continue his retreat, but had lost his entire Neapolitan loot to the looting mercenaries of the League. The looting of this treasure distracted the undisciplined soldiers of the League and prevented a complete victory. Rumors gave Francesco the blame. The devise (legend and image of the revers of the coin) argue against: Francesco's conscience is as pure as the gold melting in the crucible and is proved by God.
When King Louis XII invaded Italy for the second time in 1499, Federico moved to his side.

After his appointment as Gonfaloniere (1510), the coin design changed again:

Francesco received this title from Pope Julius II in 1510. The long center-piece mounted on Gonzagas coat-of-arms alludes to this title: Umbrella over the crossed keys Petris. The cross with the four eagles was donated by Emperor Sigismund in 1432 on the occasion of the elevation of Mantua to a margravate.

Federico II Gonzaga, 1519-1540 Margrave, since 1530 Duke of Mantua
- 5th Margrave of Mantua -   - first Duke of Mantua -
Federico (*1500) had to move to the French court as a guest and hostage in 1515, allowing his father to regain the favor of King Francis I. Federico became papal captain general and expelled the French out of Milan in 1521.
In order to win Monferrato for Mantua, Duke Federico II married the heiress of the Margravate, first Maria (1517), then her sister Margherita (1531), the last from the house of the Palaiologists. This marriage policy was successful: Emperor Charles V granted the margravate to Monferrato Federico II Gonzaga in 1536.
Federico commissioned the painter and architect Giulio Romano to build the Palazzo Te (1525-34), a pleasure seat for his constant mistress Isabella Boschetti. She could prevent the Federico's first marriage with Maria Palaiologos. Only after his death in 1540 did she withdraw.

Emperor Charles V dedicated this Impresa Federico II for his engagement in Milan 1521.
The mountain Olympus in Macedonia was considered in ancient times as the home of the gods. Just as Zeus stands above the other gods, the Emperor stands over the princes, including Federico Gonzaga. The motto 'FIDES' ("loyalty") signals the loyalty of Federico to the Emperor.

Francesco III Gonzaga, 1540-1550
- 2nd Duke of Mantua -
Francesco III (* 1533) assumed his heritage as a child under the regency of his mother Margherita Paleologa of Monferrato. Burdened with the demands of the side lines, the Gonzaga duchy fell back into insignificance. Francesco died without heirs, shortly after his marriage (1549) with Katharina of Austria, daughter of Charles's brother Ferdinand I. The duchy came to Francesco's younger brother Guglielmo. Another brother, Luigi (Ludovico) Gonzaga, married in the French aristocracy and became a patriarch of the Gonzaga-Nevers line, which replaced the extinct main line in the 17th century.

The Margravate of Monferrato became a duchy in 1574. Guglielmo was interested in ecclesiastical music and corresponded with the composer Palestrina.
While Mantua coined only with Guglielmo's name, in Casale the coinage for Monferrato took place together with his mother until her death in 1566.
