Territories of the counts of Werdenberg, Werdenberg-Sargans and Montfort in the 14th centuryCoat of arms from the Zürich armorial. The heraldic charge is a Gonfanon, derived from that of the Tübingen and Montfort coats of arms.
It is named for Werdenberg Castle, today located in the municipality of Grabs in the Swiss canton of St. Gallen, seat of the counts of Werdenberg (Werdenberger),
The family was descended from count Hugo II of Tübingen (d. 1180), who married Elisabeth, daughter of the last count of Bregenz, thus inheriting substantial territory along the Alpine Rhine. His son was Hugo I of Montfort (d. 1228), whose son Rudolf I is considered the founder of the Werdenberg line.
Rudolf's sons Hugo I of Werdenberg-Heiligenberg and Hartmann I of Werdenberg divided the southern territory of the Montfort inheritance, establishing the two lines of Werdenberg-Heiligenberg and Werdenberg-Sargans.
In 1308 Werdenberg was further divided into Werdenberg-Heiligenberg (Linzgau) and Werdenberg-Werdenberg. The Vaduz line of Counts of Werdenberg died out in 1406 and Vaduz passed to the Barons of Brandis.
The family fractured further into a number of cadet branches. The line of Werdenberg-Heiligenberg-Sigmaringen-Trochtelfingen remained influential in the early 16th century in the context of the Swabian League but was extinct in 1534.
The Werdenberg feud (Werdenbergfehde) was a major series of feuds between the
Werdenberg and their neighbours in the late 15th century, most notably their conflict with the von Zimmern family of Swabia. The feud between the lords of Werdenberg and of Zimmern escalated in 1488, rising to an importance above merely regional concerns, influencing the imperial policy of Frederick III and Maximilian I regarding the formation of the Swabian League, the Imperial Reforms and the history of the Old Swiss Confederacy.

^The last document where he appears dates from 1282, according to Neugart (1795), Tome II, MXXI, p. 313.
^The brothers share the same title/portion of land where they ruled.
^His last mention dates 18 December 1342; on 27 March 1349 he was possibly already dead.
^The pawning of the county didn't stop, however, the succession of the then titular counts: John I (1396-1400) was succeeded by his sons: Henry X (1400-1447, who recovered the county in 1436), ruled with: John II (1400-1405), George I (1400-1412), William I (1400-1412), Hugo VIII (1400-1421) and Rudolph VIII (1400-1434, was bishop of Chur).
^The annexation of the county didn't stop, however, the succession of the then titular counts: Henry V (1383-1390) was succeeded by his sons: Conrad (1390-1415) and (probably, because he's not documented after 1374) his brother, Henry VIII (at least in 1390).
^Both share the same title/portion of land in which they ruled, which suggests a co-rulership.
^This count John is officially known as IV, albeit the fact that there's no known John III in the family tree of the Werdenbergs.
^The contract of the wedding is dated 30 April 1430, according to Vanotti (1845), 41, p. 591.
^This count Hugo is officially known as XI, albeit the fact that there's not enough members of this name in the family tree of the Werdenbergs to fit this number. The last one was Hugo VIII, titular count of Sargans (1400-1421).

^This count Rudolph is officially known as X, albeit the fact that there's no known Rudolph IX in the family tree of the Werdenbergs.
