Per WP:CONTEXT and WP:MOSDATE, years, decades, and centuries without full dates generally should not be linked. For example, January2006 should not be linked, instead change it to January 2006. Also, please note WP:BTW and WP:CONTEXT, which state that years with full dates should be linked. For example, February 28, 2006, should be come February 28, 2006.
Please do not extraneously bold items outside of the bolding in the lead.
This article needs footnotes, preferably in the cite.php format recommended by WP:WIAFA. Simply, enclose inline citations, with WP:CITE or WP:CITE/ES information, with <ref>THE FOOTNOTE</ref>. At the bottom of the article, in a section named “References” or “Footnotes”, add <div class="references-small"><references/></div>.
Dates should use either 0 or 2 commas, depending upon the subject of the article; American-related articles should use 2 commas, while British-related articles generally used 0 commas. For example, for two commas: In January 15, 2006, this and that happened, while for zero commas, use: In January 152006 this and that happened.
Per WP:MOS#Headings, headings generally should not repeat the title of the article. For example, if the article was Ferdinand Magellan, instead of using the heading ==Magellan's journey==, use ==Journey==.
There are several paragraphs that are too short, which sometimes disrupts the flow of the article. These should either be expanded or merged.
