Editing 1411 (section)

=== Date unknown ===
* Under the [[Yongle Emperor]] of [[Ming dynasty|Ming China]], work begins to reinstate the ancient [[Grand Canal of China]], which fell into disuse and dilapidation during the previous [[Yuan dynasty]]. Between 1411 and [[1415]], a total of 165,000 laborers dredge the canal bed in [[Shandong]], build new channels, embankments, and [[canal lock]]s. Four large [[reservoir]]s in Shandong are also dug, in order to regulate water levels, instead of resorting to pumping water from local tables. A large [[dam]] is also constructed, to divert water from the Wen River southwest into the Grand Canal.
* [[Constantinople]] is briefly [[Siege of Constantinople (1411)|besieged]] by the Ottoman pretender [[Musa Çelebi]], due to Byzantine support for [[Süleyman Çelebi]] during the [[Ottoman Interregnum]].
* (possibly early 1412) The [[Battle of İnceğiz]] between the rival brothers [[Mehmed I|Mehmed Çelebi]] and [[Musa Çelebi]], during the [[Ottoman Interregnum]].</onlyinclude>
