Janusz I of Masovia¶

Summary¶

Janusz I of Masovia (c. 1346 - 1429), Duke of Warsaw and Czersk, is Vytautas’s brother-in-law through Danutė. In the saga he is the small, moustached, proud neighbour who gives Vytautas refuge in Czersk castle in late 1382, and is open about it: the arrival causes him more worry than joy. He is the neutral ground of the story, a Piast squeezed between the Order, Poland and Lithuania.

Years	c. 1346–1429
Status	Historical record
Note	Duke of Warsaw and Czersk; husband of Danutė Kęstutaitė and loyal brother-in-law to Vytautas.

Appearance & tells¶

Book I ch. 17: a small, moustached man, “too proud”, who has learned to survive among three stronger neighbours. He receives Vytautas in the Warsaw castle without ceremony and speaks practically: “Rest; in the meantime we will see what the world does.” His tell is caution; the Masovian house words, Między dwoma ogniami (between two fires), are the saga’s invention for the Piasts.

Want · Need · Lie · Truth¶


Want (external)	Keep Masovia out of the cousins’ wars and on good terms with every side.
Need (internal)	To be a prince who is more than a buffer.
Lie they believe	That a small duchy is safest when it is helpful to everyone.
Truth they learn (or refuse)	That sheltering a wolf costs less than refusing him (Book I ch. 17).

Arc by book¶

Book I (late 1382): receives Vytautas in Czersk castle (his capital until 1406), gives him a few weeks’ rest and guides to Prussia (ch. 17).
Later books: an offstage ally and kinsman; his brother Siemowit IV marries Aleksandra Algirdaitė (1387), so the two Gediminid lines are in-laws in Masovia.

Power & magic¶

Tier 0. A mundane prince with no gift and no bargain.

Record vs saga¶

[Historical record]: Janusz I the Elder (born c. 1346, died December 1429), Duke of Warsaw and Czersk, a Piast and from 1405 a vassal of the Polish crown. He married Danutė (Anna) of Lithuania c. 1373. Masovian troops under Janusz and his brother Siemowit IV fought on the Polish-Lithuanian side at Grunwald (1410). After Krėva, Vytautas went to Janusz’s court before going to the Order (Wigand; en.wikipedia). See Wikipedia.
[The saga’s invention]: His wary welcome and exact phrasing in Book I ch. 17. The record gives only the fact of the refuge.

Pronunciation¶

JA-nusz (/ˈjanuʂ/), English respelling YAH-noosh. Lithuanian: Janušas Mazovietis.
