This article lists dukes, electors, and kings ruling over different territories named Saxony from the beginning of the Saxon Duchy in the 6th century to the end of the German monarchies in 1918.

The electors of Saxony from John the Steadfast onwards were Lutheran until Augustus II of Saxony converted to Catholicism in order to be elected King of Poland and Grand Duke of Lithuania. His descendants (including all Kings of Saxony) have since been Catholic.

The original Duchy of Saxony comprised the lands of the Saxons in the north-western part of present-day Germany, namely, the contemporary German state of Lower Saxony as well as Westphalia and Western Saxony-Anhalt, not corresponding to the modern German state of Saxony.

Frankish king Charlemagne conquered Saxony and integrated it into the Carolingian Empire. In the later 9th century, power began to shift from the (Eastern) Frankish king to the local Saxon rulers, resulting in the emergence of the Younger stem duchy.

• Hadugato (fl. c. 531)
• Berthoald (fl. c. 622)
• Theoderic (fl. c. 743–744)

With the removal of the Welfs in 1180, the Duchy of Saxony was sharply reduced in territory. Westphalia fell to the archbishop of Cologne, while the Duchy of Brunswick remained with the Welfs. The Ascanian dukes had their base further east, near the Elbe, in what is sometimes called the younger Duchy of Saxony, resulting in the name Saxony moving towards the east. After the division, the counting of the dukes started anew. Though the first Ascanian duke is competingly counted as Bernard III (because of two predecessors of the same name before 1180) or as Bernard I, his successor, Albert I is already usually counted as the first, although before 1180 he had one predecessor of the same name, Albert the Bear.

In the 10th century Emperor Otto I had created the County Palatine of Saxony in the Saale-Unstrut area of southern Saxony. The honour was initially held by a Count of Hessengau, then from the early 11th century by the Counts of Goseck, later by the counts of Sommerschenburg, and still later by the landgraves of Thuringia. When the Wettin landgraves succeeded to the Electorate of Saxony, the two positions merged.

The new dukes replaced the Saxon horse emblem () and introduced their Ascanian family colours and emblem () added by a bendwise crancelin, symbolising the Saxon ducal crown, as new coat-of-arms of Saxony (). The later rulers of the House of Wettin adopted the Ascanian coat-of-arms.

After the division, the counting of the dukes started anew. Though the first Ascanian duke is counted either as Bernard III (because of two predecessors of the same name before 1180) or as Bernard I, his successor, Albert I is counted as the first, although before 1180 he had one predecessor of the same name, Albert the Bear.

(Note: Both lines follow the numbering established in this table until 1296, when they were created. From 1296 on, each line follows independently the succession of Saxon dukes until 1296)

However, these three nephews divided the land with him. Albert II retained Saxe-Wittenberg, and became the head of the Elder Saxon Line; Albert III, Eric I and John II ruled together in Saxe-Lauenburg, becoming the founders of the Younger Saxon Line.
			1296–1298		Saxe-Wittenberg
John I		1249	1260–1282	30 July 1285	Saxony	Ingeborg Birgersdotter of Sweden 1270 eight children
In 1296 Albert II and his nephews Albert III, Eric I, and John II ended their joint rule and divided Saxony into the Lauenburg line, where Albert III, Eric I, and John II continued to rule jointly until 1303, and the Wittenberg line, where Albert II continued as sole ruler until 1298. Since the Duke of Saxony was considered one of the prince-electors electing a new Holy Roman Emperor, conflict arose between the lines of Lauenburg and Wittenberg over the issue of who should cast Saxony's vote. In 1314 both lines found themselves on different sides in a double election. Eventually, the Dukes of Saxe-Wittenberg succeeded in 1356 after the promulgation of the Golden Bull. To distinguish him from other rulers bearing the title Duke of Saxony, he was commonly called Elector of Saxony.
John II		1275	1296–1303	22 April 1322	Saxe-Lauenburg	Elizabeth of Holstein-Rendsburg 1315 one child	Children of John I, co-ruled first with their uncle Albert II since 1282 (since the death of their father), and in 1296 split the land with him. They retained Lauenburg, which they divided once more. Albert passed the land to his widow, and after her death, in 1315, the territory was realigned: Eric divided Bergdorf with his surviving brother and held all of his brother Albert's inheritance. However, he ended up abdicating to his son, and survived for most of his reign.

The Golden Bull of 1356 confirmed the right to participate in the election of a Holy Roman Emperor to the Duke of Saxony in the Saxe-Wittenberg line.

Eric III		c.1330	1370–1401	1401	Saxe-Mölln	Unmarried	Determined to enter to clergy, has to resign to succeed his brothers. He also left no descendants, which allowed the Saxe-Ratzeburg-Lauenburg line to reunite Saxe-Lauenburg.

The numbering here leads to some confusion, as not all genealogists of the House of Ascania count John IV in the list of dukes of Saxe-Lauenburg, numbering John V (John IV's nephew) as John IV.
John IV		after 1373	1411/12–1414	1414	Saxe-Lauenburg	Unmarried
Albert IV		1375/80	11 June 1419 – (before 12 November) 1422	before 12 November 1422	Saxe-Wittenberg and Electorate of Saxony	Euphemia of Oleśnica 14 January 1420 no children	Left no male descendants, which led the Ascanian Saxe-Wittenberg line to extinction.
The Ascanian Dynasty continued in Saxe-Lauenburg until 1689, but after the Lauenburgish line had finally lost the Saxon Electorate to the Wittenberg line in 1356 and failed to obtain the succession in the Electorate after 1422, recognition of the Dukes of Saxe-Lauenburg as Dukes of Saxony waned. To follow the remnant House of Ascania in Saxe-Lauenburg, follow this table. For the following Electors of Saxony, see below the House of Wettin.

John V		18 July 1439	1463–1507	15 August 1507	Saxe-Lauenburg	Dorothea of Brandenburg 12 February 1464 twelve children	Sometimes numbered John IV. He is sometimes confused with his uncle, John IV (Eric V and Bernard IV's brother) and a son of his own (John IV, Bishop of Hildesheim).
Magnus I		1 January 1470	1507–1543	1 August 1543	Saxe-Lauenburg	Catherine of Brunswick-Wolfenbüttel 20 November 1509 Wolfenbüttel six children

The male line of the Saxe-Lauenburgish Ascanians was extinguished in 1689, after Julius Francis' death. In spite of having left two daughters to inherit the rights to the duchy, the House of Welf usurped the duchy, preventing the succession of the legitimate heiress, Anna Maria Franziska of Saxe-Lauenburg, and resucceeded with its Brunswick and Lunenburg-Celle line. In fact, George William, Duke of Brunswick-Lüneburg was a great-great-grandson of Magnus I through his great-grandmother Dorothea of Saxe-Lauenburg. His descendants became Monarchs of Great Britain from 1714 on. In 1814, after being deposed by various occupations in the Napoleonic Wars, George III's son, Regent George agreed to pass Saxe-Lauenburg to his Danish cousin in a general territorial realignment at the Congress of Vienna. This cousin was Frederick VI of Denmark, who changed the official colours of Saxe-Lauenburg to red and gold. The duchy changed hands again when, in 1865, Christian IX of Denmark was deposed in Second Schleswig War and resigned by Treaty of Vienna; Saxe-Lauenburg passed to William I of Prussia, to whom the Estates of Saxe-Lauenburg offered the ducal throne. The coat-of-arms of Saxe-Lauenburg was changed to the colours red and silver, with a border in the Prussian colours of black and white. Both duke and estates decided to merge Saxe-Lauenburg into Prussia, as district Duchy of Lauenburg, with effect from 1 July 1876.

The Ascanian line of Saxe-Wittenberg became extinct with the death of Elector Albert III in 1422, whereafter Emperor Sigismund bestowed the country and electoral dignity upon Margrave Frederick IV of Meissen, who had been a loyal supporter in the Hussite Wars. Late Albert's Ascanian relative Duke Eric V of Saxe-Lauenburg protested in vain. Frederick, now one of the seven Prince-electors, was a member of the House of Wettin, which since 1089 had ruled over the adjacent Margraviate of Meissen up the Elbe river, established under Emperor Otto I in 965, and since 1242 also over the Landgraviate of Thuringia. Thus, in 1423, Saxe-Wittenberg, the Margraviate of Meissen and Thuringia were united under one ruler, and the unified territory. gradually received the name of (Upper) Saxony (or simply Saxony).
