Marche ( , ), in English sometimes referred to as the Marches ( ), is one of the twenty regions of Italy. The region is located in the central area of the country, and has a population of about 1.5 million people, being the thirteenth largest region in the country by number of inhabitants. The region's capital and largest city is Ancona.
The Marche region is bordered by Emilia-Romagna and the republic of San Marino to the north, Tuscany to the west, Umbria to the southwest, Abruzzo and Lazio to the south and the Adriatic Sea to the east. Except for river valleys and the often very narrow coastal strip, the land is hilly. A railway from Bologna to Brindisi, built in the 19th century, runs along the coast of the entire territory. Inland, the mountainous nature of the region, even today, allows relatively little travel north and south, except by twisting roads over the passes.

From the Middle ages to the Renaissance period, many cities of the Marche were important cultural, artistic and commercial centres, the most prominent being Ancona, Pesaro, Urbino, Camerino and Ascoli Piceno.

Urbino, which was a major centre of Renaissance history, was also the birthplace of Raphael, one of the most important painters and architects of that period. The Marche region is also the birthplace of Gentile da Fabriano, Cyriacus of Ancona, Donato Bramante, Giovanni Battista Pergolesi, Giacomo Leopardi, Gioachino Rossini and Maria Montessori.

Toponymy
The name of the region derives from the plural of the medieval word marca, meaning "march" or "mark" in the sense of border zone, originally referring to a borderland territory of the Holy Roman Empire, such as the March of Ancona and others pertaining to the ancient region.
Geography
Marche extends over an area of of the central Adriatic slope between Emilia-Romagna to the north, Tuscany and Umbria to the west, and Lazio and Abruzzo to the south, the entire eastern boundary being formed by the Adriatic. The Umbrian enclave of Monte Ruperto (a subdivision of the Comune of Città di Castello) is entirely surrounded by the Province of Pesaro and Urbino, which constitutes the northern part of the region.
Most of the region is mountainous or hilly: the Apennine range runs longitudinally along the region's eastern border and descends through a hilly landscape towards the Adriatic sea. With the sole exception of Monte Vettore, high, the mountains do not exceed . The hilly area covers two-thirds of the region and is intersected by wide gullies with numerous short rivers and by alluvial plains perpendicular to the Appennini range. The main mountain range has a few deep river gorges: the best known are those of the Furlo, the Rossa and the Frasassi.
The coastline is long and is relatively flat and straight except for the hilly area between Gabicce and Pesaro in the north, and the eastern slopes of Monte Conero near Ancona.
Climate is temperate. Inland, in the mountainous areas, is more continental with cold and often snowy winters; by the sea is more mediterranean. Precipitation varies from per year inland and per year on the Adriatic coast.
A region with an annular drainage pattern possibly corresponding to a mud diapir or astrobleme exists near Sant'Angelo in Pontano.

History
Marche was known in ancient times as the Picenum territory. The first period of cultural unity of the Marches was in the Iron Age, when the region was almost entirely inhabited by the Picentes. Many artefacts from their time are exhibited in National Archaeological Museum of the Marche Region in Ancona. In the fourth century BC, the northern area was occupied by the Senones, a tribe of Gauls. The Battle of Sentinum was fought in Marche in 295 BC; afterwards, the Romans founded numerous colonies in the area, connected to Rome by the Via Flaminia and the Via Salaria. Ascoli was a seat of Italic resistance during the Social War (91–87 BC).
Following the fall of the Western Roman Empire, the region was invaded by the Goths. After the Gothic War, it was part of the Byzantine Exarchate of Ravenna (Ancona, Fano, Pesaro, Rimini, and Senigallia forming the so-called Pentapolis). After the fall of the Exarchate, it was briefly in the possession of the Lombards, but was conquered by Charlemagne in the late eighth century. In the ninth to eleventh centuries, the marches of Camerino, Fermo and Ancona were created, hence the modern name.
